'Life changing' MS drug now available in England

The first drug to help people with multiple sclerosis walk is being made available on the NHS in England.

Fampridine boosts nerve signals to make it easier for some people to move and live independently.

NHS National Medical Director Prof Frankie Swords talks about why it has taken so long for the 'life changing' drug to be available in England, when it is already available elsewhere in the UK.
