The home secretary sent official documents to her private email account six times, a review finds.
Suella Braverman has insisted there was no top secret or market sensitive information in a document she sent from her private email address.
But she has also revealed that she sent official documents to her private email account on six previous occasions.
Ms Braverman quit as home secretary after admitting breaking ministerial rules by sharing a draft immigration plan with a backbench MP.
But she was reappointed to the role six days later by new PM Rishi Sunak.
In a letter explaining her actions, Ms Braverman said she shared a draft written ministerial statement that included “high-level proposals for liberalising our migration rules” to Conservative backbench MP Sir John Hayes.
The statement was also sent to an employee Tory MP Andrew Percy by mistake.
It “did not contain any information relating to national security, the intelligence agencies, cyber security or law enforcement,” Ms Braverman said.
