Aylesbury MP David Lidington is now the new leader of the House of Commons and has had his first audience with HM the Queen.
Mr Lidington, who was Minister for Europe under David Cameron, was given the top job by Theresa May when she took office last week.
The committed Remain campaigner during the EU referendum served in his last post for six years, but says that he is glad to now have a new challenge.
He said: “Post referendum it would not have been right for me to go on when I was actively supporting a different outcome.”
Mr Lidington added: “I’m absolutely delighted to have a parliamentary role.”
Mr Lidington will work alongside leader of the House of Lords, Baroness Evans, and oversee the day to day running of Parliament.
This includes a lot of behind the scenes work, including arranging for vital structural works in the historic building.
He must also deliver a weekly business statement to the house, organise debates and meet with The Queen taking the lead in meetings of the Privy Council.
Mr Lidington was sworn into this role last week, and had to meet privately with The Queen.
He said: “It was the first time I’ve ever been in the room on my own with Her Majesty, she put me at ease, knowing that I was desperately nervous.
“She was very charming.”
