What you need to know as Southwark heads into local elections

The turnout was 34% and there was a 0.8% swing from the Lib Dems to Labour.

Labour: 52 seats (+3)

Lib Dem: 11 seats (-3)

Since the election four Labour councillors have defected to the Greens and three former Labour councillors sit as independents.

Professor Tony Travers, of the London School of Economics, said Southwark was strongly Labour-controlled but there's a powerful Liberal Democrat presence in the north of the borough, which the Lib Dems will be hoping to push south a bit.

The Greens will also be hoping to win in the southern part of the borough.

Southwark's one of a number of boroughs which could well go to no overall control, might not, but if it did it would probably be with Labour as the biggest party.

At the moment, Labour are dominant in London - they have 21 of its 32 councils, a record-equalling high.

The Conservatives run just five - having lost their former "crown-jewel" councils of Wandsworth and Westminster to Labour at the last borough elections in 2022.

The Liberal Democrats run three councils in south-west London and will be looking to gain Merton from Labour.

The Aspire Party run Tower Hamlets and two boroughs are currently in no overall control.

Nick Bowes, insight director from the London Communications Agency, said: "These are likely to be the most consequential elections in London, certainly for the past 20 years - possibly since the first borough elections in 1964."

He added: "The ways things are fragmenting in the polls it's very difficult to predict exactly what's going to happen but it does look like being a very bad night for Labour and the Conservatives in London."

More than six million Londoners can vote in the council elections on Thursday 7 May 2026.

All 32 London boroughs are up for election.

There are also elections for the mayor in five boroughs: Croydon, Hackney, Lewisham, Newham and Tower Hamlets.

Between the 14th and 16th centuries, Southwark lay beyond the City of London's control and was a hub for banned activities including bear baiting and prostitution.

The borough was also home to numerous playhouses including Shakespeare's Globe and was notorious for its brothels, licensed under the jurisdiction of the Bishop of Winchester.

In the 19th Century it was notorious for its slum-like housing and deep levels of poverty.

In 1900, the Metropolitan Borough of Southwark was formed, bringing the industrial, heavily populated area formally into London.

Destruction caused by World War Two and subsequent redevelopment schemes changed the borough's character, and in 1965 the former metropolitan boroughs, Bermondsey, Camberwell and Southwark were merged to form modern-day Southwark.

Southwark was a reliably Labour borough from its creation in 1965, until 2002 when the Lib Dems increased its number of councillors to push the council to no overall control.

Labour took back control of the council in 2010 and has since increased its number of councillors at each election.
