Sir Laurie Magnus, the chairman of Historic England, has been appointed as Prime Minister Rishi Sunak’s new ethics adviser, Downing Street has said.

Mr Sunak was under pressure to fill the role after promising to bring “integrity, professionalism and accountability” to government when he entered Downing Street.

In June, Lord Geidt became the second person to resign as Boris Johnson’s ethics adviser during the former prime minister’s premiership, and the role has been vacant since.

Sir Laurie said: “I am pleased to accept the appointment. I will endeavour to discharge the important responsibilities of the role with fairness and integrity, in a manner which inspires the confidence of Ministers, Parliament and the public.”
