Profile

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.

As Paris Fashion week gets underway, one of its most successful designers is missing from the show. Chris Bowlby looks at the life and career of John Galliano, who was sacked this week by fashion house Dior after allegedly making anti-Semitic comments.

Mary Ann Sieghart explores the life and career of Lord Patten, the Conservative peer who has achieved a number of high profile posts in a long political career. A former speechwriter for Margaret Thatcher, he became a 'One Nation' Conservative, serving in a number of ministerial roles before accepting the Chairmanship of the party in difficult political times. He steered his party to victory in the 1992 general election but lost his own seat in the process. He was quickly installed as the Governor of Hong Kong, managing the handover of the former colony to China. He also oversaw the handing over of police powers in Northern Ireland and served as European Commissioner. Now he's the preferred candidate to take control of the BBC Trust in another, new role.

"I have seen God. He bats at No 4 for India in Tests". Rob Bonnet profiles Sachin Tendulkar, possibly the most worshipped cricketer in the world.

And his name and face are used to promote eveything from luxury cars to soft drinks. Yet off the field he is one of the most reclusive players. As the ICC Cricket World Cup 2011 gets underway in Bangladesh, India and Sri Lanka, Profile discovers how Tendulkar has become India's cricket God.

As Colin Firth is honoured with a star on Hollywood's Walk of Fame, Jonathan Maitland profiles the actor hotly tipped to receive an Oscar for his performance in The King's Speech.

Colin Firth is famous for his eclectic roles and campaigning zeal. He first came to prominence in the BBC adaption of Pride & Prejudice. He played Mr Darcy, a performance he claims never to have watched in full. But his break was as a public schoolboy in Another Country. His real life was very different, he went to a state school in Winchester. At home, books and theatre were highly valued. His grandparents were missionaries which might help to explain his involvement in a number of charitable and campaigning organisations. He is particularly interested in supporting indigenous people, fair trade and foreign development. In the past he has supported Labour and came out - briefly - last year for the Lib Dems.

His career has mixed serious roles in Tom Ford's A Single Man and Michael Winterbottom's Genoa with Phyllida Lloyd's Mamma Mia and the reprisal of Mr Darcy in the Bridget Jones films.

Profile talks to his parents, Shirley and David Firth, the actor, David Morrissey and director Sir Richard Eyre.
