The new chief executive of the London Tourist Board has been named by mayor Ken Livingstone.

David Campbell, a former chief executive of Virgin Radio and the Ginger Media Group, takes up the £250,000-a-year post, in which he will have considerable involvement in the capital's bid for the 2012 Olympic Games.

He will also oversee the £15 million rescue package for the tourism industry following the war in Iraq.

However, he marked his appointment with criticism of Livingstone's comments against George W Bush.

The mayor has described the US president as "corrupt" and as representing "just about everything that is repellent in politics" - phrases Campbell said he would advise against.

"We didn't talk about it, but his attitude towards tourism is very, very positive, if a little paradoxical," said Campbell.

"I would have advised him not to say that, but he's his own man."

Although that the comments would have no long-term impact on London tourism, "repetition would not be helpful" added the new tourism chief.

"I really don't really see what the benefits are," he added.

Campbell also outlined his priorities in the role.

"As a zealous advocate of London I feel privileged to be taking up the mantle of promoting our fantastic capital," he said.

"My aim is to restore visitor numbers to this world class city, working with the industry and the mayor to leverage the wealth of diversity, culture and heritage the city has to offer."

His appointment was welcomed by Ken Livingstone.

"My Visit London plan enhanced the funding of tourism to £7 million over two years; I have also outlined the need for £15 million to recover tourism from the current downturn, £3.8 million of which is funding Totally London Month," he said.

"I look forward to working with David on implementing my vision for this crucial industry."
