John McDonnell has called for a million protesters to take to the streets to try and force another election and oust Theresa May from Downing Street.

The shadow chancellor reportedly told trade union bosses that Labour needed “every union mobilised” and for people to “get out on the streets”.

Left wing groups are believed to be plotting a mass protest in London on July 1 to demand that Mrs May step aside after she failed to win a majority in the House of Commons at the general election.

Mrs May is currently trying to hammer out a deal with the Democratic Unionist Party to prop up her minority government.

But there have been calls for Mrs May to step down and for her to offer Labour the chance to form an administration despite the fact that the Tories won the most seats and the most votes on June 8.
