“Things got out of hand and we’d had a few drinks.
We smashed the place up and Boris set fire to the toilets.”

The 36-year-old MP for Tatton is the eldest son and heir of baronet Sir Peter Osborne, the founder of the upmarket wallpaper merchants, Osborne & Little.
His real name is Gideon but he has used his grandfather's name George since the age of 13. He says: "Life was easier as a George."
At Oxford he edited the university magazine Isis. One issue was printed on hemp paper, made of the stems of cannabis plants.
After leaving university he worked for two years as a freelance journalist before landing a job at the Conservative Research Department. He was made Shadow Chancellor at the age of 33.
He lives in a £1million house in Notting Hill with his novelist wife Frances. As well as his income as an MP, he is a beneficiary of a trust fund which owns 15 per cent of Osborne & Little's shares.

After working as a banker, he trained to be a lawyer at the age of 27. He then wrote a book on his two years as a pupil barrister, My Brief Career, as well as a book on Latin, Amo Amas Amat and all that - How to become a Latin lover, for which he recently received a £130,000 advance for the U.S. rights.

With Nat Rothschild, he launched a racy publication student newspaper called Rumpus while at university which featured a topless model, a "Page 7 fella" and a guide on how to steal cars, which was frowned on by the local police.
Also featuring on the astrology page of Rumpus, wearing a wizard's costume, was George Osborne. In 2005 Coleridge, 36, founded a company called V Water which sells vitamin-infused water and now has a £1.2million turnover.

7. Nat Rothschild
Rothschild, 35, is in line to be the fifth Baron Rothschild.
After Eton, where contemporaries remember him as an unruly and wayward student, he studied history at Wadham College.
For many years, it was feared that Nat would self-destruct, like many other young Rothschilds in the dynasty.
In 1996, Nat's cousin Amschel hanged himself at the age of 41, while another cousin, Raphael de Rothschild, died in New York from a heroin overdose aged 23.
Now Nat has turned his life around, and is tipped to become the richest ever Rothschild. He is the heir to a £750million fortune and has made a second fortune in his own right by running the Atticus hedge fund, which manages funds worth £11billion.
Although discreet in his business deals, privately he lives the life one would associate with a Rothschild. His best friend is Roman Abramovich, the owner of Chelsea Football Club, and he is currently rumoured to be dating the young film actress Natalie Portman.
A skilled skier, his main home is in Klosters, Switzerland. He travels between his other homes in Paris, Moscow, London, New York and Greece in his Gulfstream private jet.
