The citizen activists oppose what they regard as the corrupted, self-serving traditional parties - the entire failed political establishment. The movement has connected with huge numbers of Italians who have developed a contempt for the governing elite.

The UK Independence Party has been in the news a lot lately: two of its supporters in Rotherham had their foster children taken away from them because of their UKIP affiliation; Conservative Party deputy chairman Michael Fabricant suggested the Tories might be wise to enter into a pact with UKIP at the 2015 general election; and rumours surfaced of a possible defection of several Conservative MPs to the anti-EU party. And then, of course, there were three Westminster by-elections in which UKIP rattled the main parties. This week, Rosie Goldsmith profiles UKIP's leader Nigel Farage.

Mary Ann Sieghart profiles the Australian political strategist Lynton Crosby.

Mark Coles profiles Abu Qatada, the radical Islamic cleric described by the Home Secretary as "a dangerous man, a suspected terrorist, who is accused of serious crimes in Jordan". Seen by some as Britain's most wanted man and Osama Bin Laden's right hand man in Europe , the Palestinian-Jordanian scholar arrived in the UK in 1993 seeking asylum and claiming he had been tortured in Jordan.

But who is Abu Qatada, a serious intellectual leader who believes in violent Jihad and accordingly to former Home Secretary David Blunkett, " a prime suspect" in the war on terror or as one friend tell us "a changed man"?

Mark Coles profiles the controversial Conservative MP Nadine Dorries, who has been suspended from her party for taking part in the reality TV show "I'm a Celebrity, Get Me Out of Here".

Dorries - a self-proclaimed council estate Scouser not afraid of speaking her mind - left school with few qualifications but went on to become a hospital nurse before setting up a successful company providing childcare services to working parents. Then she astonished her mother by entering politics.

In the House of Commons Dorries has clashed with the Opposition and many within her own party over the issues of abortion and sex education. She has sparred with David Cameron, who she regards as a "posh boy", and been criticised - even by those who like her - of being too outspoken.

According to Ian Birrell, a former Cameron speechwriter, the celebrity jungle will make or break Dorries.

"She'll either do very very well at getting across the fact she is unusual for a politician," he says, "or she will rub everyone up the wrong way and be ejected within about 20 seconds. She will be a great success or a great failure - which I think is possibly the story of Nadine.".

In a few days a 59-year-old man will almost certainly ascend to one of the most powerful positions in the world. His name is Xi Jinping and the signs are he's about to become the President of China.

But in the course of this edition of Profile Tim Franks talk to some of those who have been closest to him.
