Joyce Anelay, the minister of state for Brexit, will be replaced by Martin Callanan, the Eurosceptic peer who previously led the Conservative group in the European parliament.
Lady Anelay only took over the job after the June election, having replaced the former cabinet minister David Jones. George Bridges, another Conservative peer, also left the department at that time, and shortly afterwards it lost its permanent secretary, Oliver Robbins, to No 10.
In a letter to Theresa May, Anelay said she was standing down after the worsening of an injury sustained when she jumped to the ground on landing during a visit to Bosnia and Herzegovina while working for the Foreign Office in 2015.
Anelay, formerly a remain supporter, previously served as chief whip in the House of Lords and a minister in the Foreign Office.
May replied: “I am very sorry that your circumstances have forced you to take this decision, which I fully understand. I am disappointed that we will no longer have the benefit of your wisdom and experience in government, but I know that you will continue to contribute to proceedings in the House of Lords.”
Davis, the Brexit secretary, said Anelay had made an “invaluable contribution to ensuring a successful departure from the EU through her work representing Britain abroad, and representing the department in the House of Lords”.
As part of the mini-reshuffle of peers, Oliver Eden, whose title is Baron Henley, a hereditary Conservative peer, has replaced David Prior as a business minister, and David Cameron’s former director of operations, Liz Sugg, has been made a transport minister.
