Former London mayor Ken Livingstone has agreed to help Venezuelan President Hugo Chavez improve urban planning.
While he was in office Mr Livingstone made a deal with Mr Chavez to exchange cheap Venezuelan fuel for British buses for London's advice to mayoral candidates in Caracas.
But the current mayor Boris Johnson cancelled the deal when he came to office.
Mr Livingstone said he will personally advise officials and candidates to ensure that the country gets the "advice that we promised".
A spokesman for the Mayor of London, said: "Boris Johnson made it clear during his election campaign that he did not want to be on the payroll of Hugo Chavez and did not believe a poor South American country should be subsidising one of the wealthiest cities in the world.
"He has kept that promise to the people of London. Ken Livingstone is free, as a private individual, to offer his advice and services to whomever he wants."Reuse content
