Jo Johnson backs bid to force Treasury to reveal no-Brexit forecasts

Ex-minister expected to make first speech from backbenches to support amendment to the finance bill

Jo Johnson, the Conservative MP who resigned as a minister to back a second Brexit referendum, will on Monday throw his weight behind a bid to force the government to publish economic forecasts that compare its deal with remaining in the European Union.

The Orpington MP is expected to make his first speech from the backbenches to support a cross-party amendment to the finance bill. Tabled by Labour's Chuka Umunna and the Conservative Anna Soubry, the amendment is backed by 70 MPs from six parties, including the Liberal Democrat leader, Vince Cable, and the SNP's Europe spokesman, Stephen Gethins.
