The PM took a tour around the hospital this morning (October 31) - the date that he had insisted Brexit would happen.

He spoke to Dr Anna Godfrey during a visit to the National Institute for Health Research at the Cambridge Clinical Research Facility.

Speaking at the hospital, Boris Johnson said: "The NHS has been there for all of us.

"We're investing more than ever before so it can provide world-class care."

He left the site just after 1.30pm to visit a primary school in Bury St Edmunds.

Earlier this week, it was announced there would be a general election on December 12.

After months of Brexit deadlock, he has now accepted the EU's offer of a Brexit extension until January 31.
