David Cameron's appointment as Foreign Secretary in Rishi Sunak's government is notable, as he joins the ranks of former prime ministers like Alec Douglas-Home and Arthur Balfour who have returned to high-level government roles. He will serve from the House of Lords, similar to previous Foreign Secretary Lord Carrington under Margaret Thatcher.
Cameron's return, however, is not without controversy. His involvement in the Greensill lobbying scandal and his role in initiating the Brexit referendum have drawn criticism.
Additionally, his foreign policy decisions during his tenure as Prime Minister, such as military intervention in Libya and relations with China, add to the foreign policy baggage he brings to his new role.
Despite these concerns, Cameron's extensive experience and international relationships could be advantageous in navigating current global challenges. His stance on issues like development aid, where he previously supported the UK's commitment to spending 0.7% of national income, will be closely observed.
The impact of his return on the UK's foreign policy and diplomatic efforts remains to be seen.
