Suella Braverman has admitted she sent official documents from her government email to her personal address on six occassions.
The Conservative MP resigned as home secretary less than two weeks ago in the final days of Liz Truss’ premiership.
Braverman claimed at the time that she had chosen to resign because she had sent an official document from her personal email in a breach of security rules.
However, she was reappointed to the role just six days later after Rishi Sunak was named as the new prime minister.
She said that she had apologised to Sunak and assured him that she would not use her personal email for official business.
In a letter to Westminster’s Home Affairs Committee, Braverman reiterated her apology.
Braverman also gave further details of the security breach and confirmed that she had sent official documents from her government email to her personal address six times between September 6 and October 19.
She said that those were on occasions when she was conducting meetings virtually or related to public lines to take in interviews.
“None of the documents in question concerned national security, intelligence agency or cyber security matters, and did not pose any risk to national security,” she told the committee.
“None of the documents were classified as SECRET or TOP Secret.”
Dame Diana Johnson, who chairs the committee, has said that Braverman should come to the Commons in order to explain her position.
“She’s got to deal with this because until this is dealt with, she can’t get on and do the job of home secretary,” said Johnson.
It was confirmed after Johnson’s remarks that Braverman would appear in the Commons on Monday afternoon.
The Prime Minister’s official spokesperson said that Braverman had set out a “detailed account” of the breach that triggered her resignation.
They told journalists: “She has provided a detailed account around those issues, both the individual issue of forwarding that email and a further investigation.
“I think she has set out in quite a lot of detail what has happened and the mitigations that have been taken.
“Clearly, as she makes clear, she made an error of judgment.
“She recognises that the approach she took was not right and it is for those reasons that she felt it was right to resign.”
