Momentum, the pro-Jeremy Corbyn group, has set up training camps to get rid of Boris Johnson and other Conservative MPs in marginal seats.

Using the hashtag #UnseatBoris and #UnseatIDS, activists make clear their plans to remove the Foreign Secretary and the former Work and Pensions Secretary from their seats.

Some prominent campaigners and writers, including Owen Jones, have already visited Boris Johnson's seat to speak to voters. They were joined by MPs including Rupa Huq and Emily Thornberry.
