We've just heard that one of the counting teams has finished verifying ballot papers.
There are 12 of these teams, spread over two floors in the Camden Council main office.
That team will now move on to counting, while the other teams will continue verification and then move on to counting ballot papers.
The vote counting is now underway.

The prime minister said the motion, approved on Sunday at the party's conference in Brighton, was "completely wrong" and showed "terrible judgement".
The motion defined Zionism as an ideology supporting "an ethnonationalist Jewish state" and backed a "single democratic Palestinian state in all of historic Palestine", which includes modern-day Israel.
In the wake of the vote, Polanski has said he would not accept anyone being excluded from the Green Party "because of the religious or communal body they are part of".
Caroline Lucas says the Green Party was always going to have "a major hill to climb" in today's by-election, given its history as a Labour stronghold, but still feels the party will do well.
The former Green leader says she thinks it was a "mistake" that Zack Polanski did not vote in the Green Party motion on Zionism over the weekend, but declined to answer whether he should stand down as party leader.
Lucas opposed the new policy, which declared Zionism as a form of racism.
She tells Newsnight: "I would have hoped he would have been a very strong critic of this motion. The motion was flawed from top to bottom - in my view it is dangerous, it is divisive."
Lucas adds: "I know an awful lot of people are hurting out there now, particularly in the Jewish community, and I am very sorry."

Party members are standing over them eagerly writing on clipboards.
Some of them are reading polling cards to get an idea of how their party is doing in each polling district, and to potentially inform their campaigning going forwards.
They will also use their tallies to gauge how their candidate is doing throughout the night, and feed those predictions through to journalists.

The deputy leader of the Labour Party says: “Sagal came to Britain as a child refugee, fleeing a war-torn country. Educated in great Labour Camden schools, she’s been giving back to her local community ever since."
She continues: “If the voters of Holborn and St Pancras put their trust in Labour, I know that Sagal will work hard every day to make life better for each and every person across the constituency.”

The Green Party has put out a statement following the closure of polls in the Holborn and St Pancras by-election.
A party spokesperson says: "Zack would like to thank the thousands of volunteers who helped him in this campaign."
They say the party leader, who is also the Green's candidate in the by-election, would "like to pay tribute to Sagal, for a respectful campaign and for rising above the appalling racism she has had to endure. Despite our political differences, we stand in solidarity with you".
The statement continues: "Whatever the result later, we've run a positive campaign full of energy in what is one of Labour's safest seats. To be the main challenger, shows how far the Greens have come.
"Whether we win or lose, this evening, keeping the pressure on the Labour government to deliver on these priorities will be our focus."
Image source, PA MediaWhen Keir Starmer announced his resignation as prime minister earlier in June, he said he would stay on as an MP until the next UK general election, which is not due until 2029.
But in a surprise statement - hours before his successor Andy Burnham made his debut in the House of Commons - Starmer said he would leave his post as an MP, triggering a by-election in Holborn and St Pancras.
Starmer said he was resigning to work on issues such as international affairs and violence against women and girls.
He told the Camden New Journal, external it had been a "huge honour and privilege" to represent the London constituency for 11 years, ending weeks of speculation about whether he would remain an MP.
It now leaves his parliamentary seat in Holborn and St Pancras empty, and 15 candidates are waiting at the ballot box hoping to replace him.

More and more people are arriving at the count today after polls closed a short time ago.
We are expecting ballot boxes to start arriving in the next hour.
The counting here at Camden Council’s main office is spread over three floors - 144 counting staff are positioned on long tables on the upper two floors, with media below.
There has been an energetic buzz about the building as counters prepare for the night ahead, and they’ve just had an announcement to begin verification of postal ballot papers.
The big job tonight has begun.
I’ve seen party members milling around where the counting is taking place - red, blue and yellow rosettes indicate their affiliation to Labour, the Conservatives and Liberal Democrat parties.
Briony Kapoor, the candidate from the Rejoin EU Party, has also just arrived.
More journalists have also trickled in, and at least a couple Metropolitan Police officers.
Voters could be seen leaving polling stations across Holborn and St Pancras today after casting their ballots in today's by-election.

Holborn and St Pancras is a parliamentary constituency full of well-known London landmarks, from the British Museum and the BT Tower to Primrose Hill, Camden Market, and bits of Regents Park.
The north London seat stretches from Holborn, Russell Square and Bloomsbury, up past Camden Town to Chalk Farm and Kentish Town.
It’s a place where many visitors first arrive in London through the major tube and railway stations at Kings Cross, and at Euston, where construction work continues for the development of HS2.
The constituency has a lot of young people. 20-24 year olds make up the largest single age group, and just under half of its residents are aged under 30 years old, according to the latest census.
While the constituency has many affluent neighbourhoods, it is a place where the cost of living and, in particular the cost of housing, is acute for many of its residents.
It is a very expensive place to buy or rent a home, and according to figures in the last census, a significant proportion of its residents (43.3%) live in social rented housing. It’s also a part of London that has high levels of child poverty.

We’ve just heard from acting returning officer Jon Rowney who leads everyone here at the count through the plan for the night ahead.
He stresses that the secrecy of ballot boxes is paramount and no pictures should be taken that could identify what a constituent has voted.
He says ballot boxes have been assigned to each team of 12 counters so that they finish at around the same time, rather than by geographical areas like wards, and thanks them for their “essential” work.
Finally, Rowney says counting will begin at 22:00 sharp, with postal votes, as we await the arrival of the ballot boxes from voters who have come to the polls throughout the day.

This feels like a consequential and rather crunchy by-election for several reasons.
For a start, it is only happening because of the national politics of the last few years – and the resignation of Keir Starmer as prime minister. Not long after he left Downing Street, he decided to leave parliament too – vacating his seat here in Holborn and St Pancras in north London.
It is also the first by-election of Andy Burnham’s tenure as prime minister. It has been a safe Labour seat for a long, long time but the Green Party of England and Wales has been making waves since Zack Polanski became its leader – and the party performed well in the local elections in London in May.
So it is a test for Burnham and it is a test for Polanski, who is the Green candidate in this race.
Image source, ReutersAnd that is where things get rather heated, given the huge row of the last few days.
The Green Party is currently eating itself alive over a motion passed at its party conference just a matter of days ago which led to Polanski being banned from Israel and his party face criticism not just from the Jewish Leadership Council and the Board of Deputies of British Jews but also from sister green parties in Europe.
Polanski, who himself is Jewish, didn’t vote on the motion which said Zionism is a form of racism and called for a single Palestinian state, meaning no Israel.
The motion passed. Polanski’s team said he was instead campaigning here in Holborn and St Pancras at the time.
He has been saying no to interviews with journalists in the last few days – the BBC’s requests have been declined.
When my colleague Emilia Belli found him campaigning earlier today, she politely but persistently put questions to him, but he didn’t answer them.
Meanwhile, the prime minister has weighed in, arguing that the motion amounted to “a completely wrong decision, a terrible judgment on the part of the Green Party of England and Wales - in effect, ruling out a two-state solution between Israel and Palestine, and for that reason it shouldn’t be supported in any way, shape or form.”

Responding to that, the Green Party of England and Wales have put out this statement:
“This has been an emotive issue and is complex. It has rightly caused much discussion, and needs to be taken in the context that Israel’s behaviour has had. Israel has been responsible for a genocide, ethnic cleansing and the killing of children, and we've had a political establishment which has not only turned a blind eye but provided support.
Zack has made an unequivocal commitment that no Jewish person will be excluded or denied a voice because they are a member of a synagogue or communal organisation that endorses Zionism.”
One figure in the party said to me that “Zack has created a monster that he either can’t or won’t control.” Plenty in the party are livid.
We expect to get to put some questions to Polanski after the vote – it will be very interesting to see how he answers them, and how, even whether, he can move the party on from the biggest row of his leadership so far.
As for the by-election contest, the Greens sound decidedly less upbeat about the result than Labour do.
Polls have now closed in the Holborn and St Pancras by-election.
