A second Sussex MP has quit the Cabinet during a reshuffle by the Prime Minister.

Jeremy Quin, MP for Horsham, announced he would be resigning from his role as Paymaster General to “concentrate on projects” in the town.

Mr Quin had been asked to continue to serve in government by Prime Minister Rishi Sunak but refused.

In a letter to the Prime Minister posted on social media, Mr Quin said it had “been an honour to serve in government since 2018”, having previously served as a government whip, defence minister and minister for policing.

He said: “It has been a pleasure to support you consistently and I look forward to doing so in the future.

“I wish you well as you focus on the long-term decisions for our country.”

Mr Quin is the second MP from the county to resign in today’s Cabinet reshuffle, with MP for Bognor Regis and Littlehampton Nick Gibb stepping down from his role as schools minister.

Mr Gibb also announced he would not stand for re-election in 2024, becoming the third MP in Sussex to say they will stand down when voters next go to the polls, alongside Conservative MP for Crawley Henry Smith and Green MP for Brighton Pavilion Caroline Lucas.

In a post on social media, he said it had been a “privilege to represent the people of Bognor Regis and Littlehampton over the last 26 years” but also hit out at “growing cynicism and hostility to those who stand for election and hold office”, claiming it is “damaging our ability to come together to solve problems”.

In a surprise move in today’s reshuffle, former Prime Minister David Cameron has been made a member of the House of Lords and become foreign secretary.

Lord Cameron is the first former Prime Minister to hold a Cabinet position since Alex Douglas-Home, who also became foreign secretary after serving in Number 10.

Suella Braverman has been sacked as home secretary and replaced by James Cleverly.

Environment secretary Therese Coffey has also left her job, with the reshuffle continuing into the afternoon.
