He's a popular figure in the Conservative Party and a key player in the Coalition, but this week the Foreign Secretary, William Hague, was criticised after a bungled SAS mission into Libya. The Prime Minister has defended him, but others are asking whether Hague still has a passion for politics at the highest level. As Tory leader in 2001, he led his party to a crushing defeat and announced his resignation the day after the election. Over the next few years, he enjoyed a rise in popularity, probably helped by appearances on the TV show, 'Have I Got News for You'. Now, back at the top of the political game, he's again facing challenges which are testing his mettle.
