'Vote for the one who stands on principle'

Gina Miller puts the case for tactical voting in the general election to endorse candidates opposed to a 'hard Brexit'.

In a personal film for This Week, the woman who took the government to court to ensure MPs had a vote on Article 50, said: "I urge you - look closely at what candidates say on the issue, and vote for the one who stands on principle and does what best for Britain."
