Speaking after today's meeting of the London Assembly's Business Management and Administration Committee, which examined Deputy Mayor Ian Clement's misuse of a corporate credit card, Mike Tuffrey leader of the Liberal Democrat group on the London Assembly said:
"Since March 2009 the Mayor has been personally responsible for approving the expense claims of his Deputy Mayors.
"Serious questions remain about why Boris Johnson personally approved these claims, when staff knew there was a history of irregularities. The Mayor now needs to come and explain himself to the Assembly.
"Attention also has to turn to scrutinising the thousand of pounds in other expenses that Ian Clement has claimed, but which do not appear on the GLA's corporate credit card statements.
"For the future, there must be line-item disclosure of individual expense claims for the Mayor, for all mayoral advisers and Assembly Members, on-line and available to the Audit Committee."
