BREXIT ministers were accused of not fully reading reports about the impact of leaving the European Union on different sectors of the economy.

Steve Baker and Robin Walker insisted they were kept up to date with the findings but had to prioritise their time.

Prime Minister Theresa May has been challenged over whether she has read the documents, which have not been made public because of official concerns they could damage the Government’s negotiating position.

At the Exiting the European Union Committee, Labour MP Seema Malhotra challenged the two ministers about the 57 sets of sectoral analysis. Asked if they had read the reports, Baker said: “I have read a very great amount of material, day in day out.

“We have a developing view of everyone’s interests, on our side and the other side, and we keep all this information under review and refer to it as required.”

Malhotra replied: “It sounds to me like both of you haven’t fully read those reports that you say can’t be published because they could jeopardise the negotiations.”

Baker said: “In the roles that we have, we must ruthlessly prioritise our time. Some of that material I have read in great detail. I have not read all of the documents which we have.

“All of the documents which we have is a very large amount of material and I am scrupulously, ruthlessly, focused on my priorities.”

Walker told her: “We have been consistently kept up to date with the latest analysis on all these things.”

Asked who had read the documents in order to decide they could not be published, Baker said: “We have teams of economists and policy civil servants who are fully abreast of our analysis.

“This analysis is material to the negotiations and we – Parliament – has voted twice not to disclose material which could damage those negotiations.”

On Wednesday, Brexit Secretary David Davis said May would know the “summary outcomes” of the documents, which went into “excruciating detail”.

Malhotra has now written to the Prime Minister asking how much she had seen of the reports. Baker and Walker insisted the Prime Minister was kept “well informed”.

Malhotra said: “We are on the brink of the biggest change to our country’s economy for generations.

“It is staggering to hear David Davis suggest the Prime Minister has not even read the most important reports the Government has undertaken on the economic impact of Brexit.”

Meanwhile, a senior Tory MP has said she and her colleagues are “deadly serious” about backing plans to give MPs the final say on Britain’s Brexit deal.

Nicky Morgan challenged Brexit Secretary David Davis over reports that Tory rebels were not serious about backing an amendment to Brexit legislation that would put any vote on the statute book.

The amendment to the European Union (Withdrawal) Bill has been tabled by Tory former attorney general Dominic Grieve, who said such a move would calm the debate and “bring a bit of rationality” to negotiations. For Labour, shadow Brexit secretary Sir Keir Starmer also pushed for a “meaningful” vote by MPs on the final Brexit deal to be guaranteed in law.

An urgent question was tabled in the Commons after Davis was forced on Wednesday to row back on claims that MPs may only be given a vote on the deal after the country had left.

Speaking in the Commons, former Cabinet minister Morgan said: “There is a way for the Government to put this matter completely beyond doubt, and that is to accept the amendment seven to the Withdrawal Bill laid by [Grieve].
