Boris Johnson’s battle bus was mobbed by protestors as the prime minister arrived in Derbyshire to drum up support on Thursday.

Johnson was in the east midlands’ Matlock as the general election campaign reaches its final seven days and was greeted with chants about the NHS and austerity, 

The bus was “surrounded” according to reporters at the scene, nearby where Johnson was due to take part in a Q&A session with workers at the John Smedley factory. 

It comes amid fears a trade deal between Donald Trump’s US administration and the UK could include the NHS. 

Speaking to ITV earlier in the day, Johnson described the idea as “complete nonsense”.

Referring to a leaked document which appeared to show that pharmaceutical US firms want “total market access” after the UK leaves the EU, Johnson said: “And there are photographs that purport to prove there are UFOs. But it is complete nonsense.”

It comes the same day as the PM apologised over a previous Telegraph article in which he likened women wearing burkahs to “letterboxes” and “bankrobbers”. 

Speaking to ITV, he said: “I have already said sorry for any offence that I’ve caused, and I say it again.”
