The document discusses whether the role of the Prime Minister in the UK has become similar to a president. It notes that PMs now have increased importance in foreign affairs and as commander-in-chief. Additionally, the growth of special advisers and the PM's media profile separates them from the government and portrays them as a lone leader. However, the PM is still not head of state and does not have a separate authority from the rest of the government like a president. The document analyzes how the powers of several past PMs, like Thatcher and Blair, have grown in a more presidential style.
