Prompt
Generate a realistic portrait of Frederick Montague, 1st Baron Amwell, a British politician and member of the Labour Party, in a formal attire, possibly with a suit and tie, and a subtle background that hints at his parliamentary career, such as a faint image of the Houses of Parliament or a British flag. The style should be traditional and dignified, reflecting his title and position as a Member of Parliament and Under-Secretary of State for Air.
