Crime author Peter James steps up his feud with Martin Amis Beating bullies The Duchess of Cambridge, who asked her wedding guests to donate to an anti-bullying charity, is not the only member of the Royal family to stand up against children's tormentors. Mandrake hears that Prince Harry has lent his support to a campaign led by Ben Cohen, the former England rugby player, Stand Up Against Bullying. "Harry loves what we are doing with Stand Up," says Cohen. At the age of 13, the Prince's sister-in-law left Downe House school after just two terms, having been targeted by bullies. Send Shard man to Tower Inaugurated by the Duke of York, with a spectacular light show, the Shard has, however, failed to impress Prof Edward Jones, the distinguished architect behind the sensitive redevelopments of the Royal Opera House and the National Portrait Gallery. The Shard, which is Europe's tallest skyscraper, is a "really terrible building," according to Prof Jones. It's a ridiculous notion to put a 1,000ft building in a side street. It makes all the buildings around it suddenly look useless and pathetic. It does no service to the city. Renzo Piano designed the Shard and Prof Jones is no fan of the Italian's other London projects, which include the Central Saint Giles development known for its striking, coloured tiles. "Maybe we should ban him from building here because he is a monster," says Prof Jones. We should put him in the Tower of London to contemplate his folly across the river. Club leaves a hole in polo When Cartier announced that it was withdrawing its sponsorship of the International Polo tournament at the Guards club after 26 years, the jeweller was said to be keen to disassociate itself from the rowdier spectators that the event attracted. Audi, the new sponsor of what was the highlight of the polo season and previously attended by members of the Royal family, said it was relaxed about the "chavvy" element lured to Windsor Great Park by the entertainment provided by Chinawhite, the nightclub. Now, however, the Hurlingham Polo Association, the sport's governing body, seems to have changed its mind, as Mandrake can disclose that Chinawhite has been dropped from the event, just two weeks before it takes place. A Chinawhite spokesman insists that it pulled out because of the rain. "The weather has been disastrous for ticket sales," he tells me, adding that the nightclub will return to the event in the future.
