He is one of a small number of people who has made it to both the North Pole and the South Pole. He runs ultramarathons. He climbs mountains. Oh, and he is a billionaire, one of the country's richest men, who has reluctantly been making the headlines. Jim Ratcliffe, who recently threatened to close the huge Grangemouth petrochemical plant in Scotland - which he owns through his company Ineos - is often described as 'reclusive'. Certainly he doesn't seek publicity. In Profile this week, Jo Fidgen talks to those who know him best, to find out what makes Jim Ratcliffe tick.

Last year, long-standing Conservative MP Andrew Mitchell was forced to resign his new job as Chief Whip after being accused of calling police officers guarding the Downing Street gates "plebs." The so-called 'Plebgate' saga has hit the headlines once again this week after a committee of MPs summoned three senior police officers to explain their inquiry into the incident. While last year Andrew Mitchell was the focus of controversy, the Rugby and Cambridge-educated disciplinarian is now eliciting sympathy in many quarters.

Mary Ann Sieghart looks at the making of a director whose work includes collaborations with Damon Albarn and the London Community Gospel Choir and a musical about a real-life serial killer.

This week saw the surprising exit from the English Defence League of its leaders Tommy Robinson and Kevin Carroll. Instrumental in their decision to leave was Essex-born Maajid Nawaz, a former activist for the Islamist organisation Hizb ut-Tahrir. Arrested in 2001 for attempting to revive the group in Egypt, he served four years in a Cairo jail. Today, he has renounced his old beliefs and now runs the Quilliam Foundation, a 'counter extremism' think tank run by former activists. He has also been selected by the Liberal Democrats to fight a marginal parliamentary seat in 2015. Mark Coles looks at his life.

Iran's new president Hassan Rouhani has been centre of attention at the UN this week. He's promising a new approach to talks with the West over his country's nuclear programme.

He is certainly a change from his abrasive anti-Western predecessor. Rouhani studied in Britain, loves Bogart films and Thomas Hardy novels and is fond of designer clerical robes.

So, Mary Ann Sieghart asks, is all that merely a matter of presentation? Or is he a completely new kind of Iranian leader?
