Brexit vs no Brexit economic forecasts will be revealed after pressure on Government

The Government is to publish economic forecasts comparing Theresa May's Brexit deal with the UK remaining in the EU following pressure from MPs.

Eleven Conservatives, including former minister Jo Johnson who quit over Brexit and Anna Soubry, were among 70 MPs to sign an amendment to a Budget Bill in the House of Commons on Monday.

Leading Labour Remain campaigner Chuka Umunna put forward the amendment that sought to force the government to publish economic forecasts on the Prime Minister's EU withdrawal agreement, a no-deal Brexit and remaining in the UK.

Treasury Minister Robert Jenrick conceded that the government would release a comparative analysis of the three scenarios.

Previously, the government had only pledged to publish an assessment of the impact of leaving the EU with a deal compared to leaving with no deal.

Labour MP Mr Umunna, a leading supporter of the People's Vote campaign who tabled the motion, said it showed the growing support for a second EU referendum.

He said: "This was the first test of strength facing the People's Vote campaign in Parliament since the government published their draft deal, and it is one that we in the campaign have won after gaining support from all sides of the House.”

The economic forecasts will be published before MPs vote on Mrs May's withdrawal bill in Parliament.

The latest development comes as Prime Minister Mrs May’s DUP coalition allies accused her of breaking “fundamental” promises on Brexit.

And the party made its unhappiness clear when it cut the government’s majority to just five on a vote on the Budget in the Commons on Monday.

Under the terms of the DUP deal, agreed after Mrs May lost her parliamentary majority after her disastrous general election, the Northern Irish party is supposed to prop up the Conservatives in Commons votes.

But DUP Brexit spokesman Sammy Wilson said Mrs May's deal with Brussels breached a "fundamental" assurance that Northern Ireland would not be separated constitutionally or economically from the rest of the UK.

"We had to do something to show our displeasure," he told BBC2's Newsnight.
