Ex Goldman Sachs man to join Johnson campaign

Conservative mayoral contender Boris Johnson speaks during their spring forum in Gateshead, March 14, 2008.

LONDON (Reuters) - Conservative candidate Boris Johnson unveiled several more prominent advisors on Monday who will join his team if he is elected Mayor of London.

Retired Goldman Sachs banker Richard Sharp, former Labour donor Trevor Chinn, charity fund-raiser Wasfi Kani and former prison governor Ray Lewis are amongst the group who have agreed to help Johnson manage the Mayor's Fund, the Tory candidate said in a statement.

They join Barclays President Bob Diamond, 56, who was the first person identified as a potential adviser by Johnson ahead of the mayoral election on May 1.

Johnson told a Reuters Newsmaker event last week that the U.S.-born Diamond would help him find sponsors for the fund that is designed to tap private wealth to tackle London's social problems.

"The Mayor's Fund means a great deal to me -- I want my mayoralty to be successful in helping London's teenagers make the right life choices," Johnson said in a statement.

"I am delighted that so many prominent people in London have pledged their time to making it (the fund) a success and can see the value of the scheme."

Johnson has been under pressure to say who will serve on his team if he is elected, following accusations that he has neither the management experience nor organisational skills to run the capital and its 11 billion pound budget.

His leading rivals, incumbent mayor Ken Livingstone and former police chief Brian Paddick, say Johnson, a former journalist, lacks experience of high office and has not run anything more complex than a political magazine.
