Theresa May and Boris Johnson are in Slough this evening in a final attempt to gain votes in the hotly-contested constituency. 

Mr Johnson introduced Mrs May to the stage at Slough Trading Estate.

As reported in the Observer, the Tories are aiming to take Slough from Labour.

It's been a Labour stronghold for 20 years.

Mrs May has reportedly said she could look to change the Human Rights law if it stops the government dealing with terrorists.
