Home secretary and Fareham MP Suella Braverman under attack as backlash grows against her reinstatement in the cabinet

Labour will try to force the government to publish its assessments of Fareham MP Ms Braverman’s security breach, as the backlash grows against her reappointment in the senior cabinet post.

Prime minister Rishi Sunak has resisted demands to launch an inquiry into Ms Braverman breaking the ministerial code by sharing a sensitive document with a Tory backbencher from a personal email without permission.

Both Labour and the Liberal Democrats have raised ‘national security’ concerns and called for a probe.

Labour will push ministers to share risk assessments of this and other alleged leaks, as well as the information given to Mr Sunak before he reinstalled her, with a ‘humble address’ motion in parliament.

Ms Braverman has so far refused to appear before MPs to explain what happened.

Shadow home secretary Yvette Cooper said: ‘Rishi Sunak and Suella Braverman cannot keep running away from these questions. It is far too serious for that, and raises serious doubts about the prime minister’s judgment.

‘People need to know they can trust the home secretary with highly sensitive information and our national security.

‘Labour will use every parliamentary mechanism open to force government to come clean over her reappointment, to get answers and to require detailed documents to be released to the Intelligence & Security Committee.’

Labour leader Sir Keir Starmer has demanded the home secretary’s sacking, accusing Mr Sunak of brokering a ‘grubby deal trading security for support’ in the Tory leadership contest, which he won after receiving Ms Braverman’s backing.

But the PM has insisted Ms Braverman has ‘learned from her mistake’ and that he does not regret the appointment despite some Conservative MPs adding their voices to the backlash.

Caroline Nokes backed opposition calls for an inquiry and former Tory chairman Sir Jake Berry described the breach as “really serious”.

Ms Braverman – dubbed ‘Leaky Sue’ – was reportedly previously investigated by government officials after the leaking of a story involving the security services.

The Daily Mail reported that MI5 played a role in the inquiry after the leak at the time Ms Braverman was attorney general sparked ‘concern’ in the security service.
