Nigel Farage urged to stand aside in Tory target seats after climbdown

Brexit party will not contest Conservative seats but source says it will pursue Labour-held ones

Nigel Farage is facing calls from Brexit supporters to stand down further candidates to help Boris Johnson after he made a dramatic public U-turn by agreeing to withdraw his party from all Conservative-held seats.

The Brexit party leader claimed he had changed his mind about fielding candidates in 317 seats held by the Tories after Johnson released a video pledging to take Britain out of the EU by 2020 and to pursue a Canada-style trade deal.
