Brexit secretary David Davis has finally revealed the list of sectors for which his department has carried out Brexit impact assessments.
Fintech, asset management, banking and professional services are among the 58 sectors that were studied by officials at the Department for Exiting the EU, although the findings will remain confidential.
Writing to the committee, Davis stressed that it must remain in a "safe space" to prevent affecting negotiations.
He said: "There is a strong public interest in policy making associated with our exit from the EU being of the highest quality and conducted in a safe space to allow for design and deliberation to be done in private. In this case, releasing the commissioning document for this exercise, which is still a live policy issue, may undermine the effective formulation or development of policies which are key to our negotiating strategy. Disclosure would similarly set a precedent that would inhibit free and frank discussion in the future.
"Without the necessary safe space for unreserved instruction in commissioning briefs, the quality of the eventual advice from the respective exercise would be diminished and would in turn lead to poorer decision making."
But Labour MP and member of the Exiting the EU select committee, Seema Malhotra, claimed Davis' refusal to publish further details was less about protecting sensitive negotiation details and "more about keeping parliament and the public in the dark".
She said: "Industry must have confidence that their concerns are understood and being responded to. Business needs clarity and certainty."
Malhotra added: “Where there are clear reasons for confidentiality I hope an agreement on confidentiality procedures can be agreed between Government and Parliament in order for Parliament to be able to play its part.”
Rachel Reeves, chair of the influential Business, Enterprise, Innovation and Skills (BEIS) committee, told City A.M. "I don't think that pressure [to be transparent] is going to disappear any time soon." She agreed with Malhotra that industry needed to know that their concerns had been listened to, adding that Parliament must be able to have "an informed debate".
Davis is scheduled to lead a Cabinet discussion on Brexit preparations today, which will look at "preparations for all contingencies", including those of a no deal scenario, a Downing Street spokesman said.
