The mayor of London had made 10 appointments to the board of Transport for London.

It was confirmed on Tuesday that controversial union leader Bob Crow would not be taking a seat on the committee in Ken Livingstone's second term at City Hall.

TfL oversees the entire transport strategy for the Capital and meets regularly to advise the mayor and senior executives.

The RMT general secretary resigned last week after he fell out with Livingstone over the London Underground staff strike.

The mayor had been expected to offer Crow the olive branch of the appointment but was snubbed before he had the chance.

Instead he announced two new names: Transport and General Workers Union regional organiser Patrick O'Keeffe and John Ormerod, a former senior partner at accountants Deloitte.

Along with Crow, three former members were not reappointed: TGWU official Oli Jackson; former Aslef assistant general secretary of Tony West; and transport professional David Quarmby.

Murziline Parchment, a policy adviser to Livingstone, loses her seat on the board but becomes one of three special advisers to it.

Unions may be concerned that three labour movement representatives have lost their seat while only one has been added to the board.

However a statement stressed that other members have "union experience" and that more names have yet to be unveiled.

"I intend to appoint 10 people to the TfL Board, plus three special advisors. I will continue to chair the board, reaffirming my commitment to improving transport across London," Livingstone said.

"I expect to be able to announce appointments to the remaining four places on the TfL board shortly."
