Pack up your troubles ... Kiley leaves London

A removal firm was seen loading possessions from the £2.1 million Belgravia townhouse bought for him by Ken Livingstone.

Mr Kiley, 71, earned about £2 million as the head of Transport for London but quit TfL last year with an additional £1 millionplus "golden farewell" and the promise of earning £3,200 a day as the Mayor's personal consultant. But no record was kept of his workload, leading critics to dub him "No job Bob".

The consultancy deal collapsed when Mr Kiley suffered a renewed bout of alcoholism and admitted to the Evening Standard in March that he did "not much" for his money.

Mr Kiley, who headed TfL during the introduction of the congestion charge and fought the part-privatisation of the Tube, recently underwent hospital treatment for alcoholism in America and is not expected to work again in London.

Today opposition politicians expressed sympathy for Mr Kiley's plight but condemned the secrecy around his contract.

Roger Evans, Tory chairman of the London Assembly's transport committee, said: "It was an amazingly generous salary but the results have been somewhat mixed. I think Londoners are still entitled to question whether they got value for money."

Geoff Pope, Liberal Democrat transport spokesman on the Assembly, said: "This consultancy deal was one of Ken's costliest mistakes. The decision to sweeten Bob Kiley's deal with a £2 million house was a smack in the face of the thousands of Londoners who are fighting to get onto the property ladder." Damian Hockney, leader of the One London party on the Assembly, criticised the "complete lack of transparency" surrounding Mr Kiley's deal. "It was clearly a pay-off disguised as a consultancy," he said.

TfL stands to make a handsome profit on the house. Smaller neighbouring properties in Ebury Street are being marketed for £2.75 million. A TfL spokesman said: "We can confirm that Mr Kiley has vacated the Ebury Street premises. The house will now be sold. On its current valuation TfL expects to make a sizeable profit."

Mr Kiley quit as TfL commissioner in January last year amid reports of infighting with senior officials. He went on to advise the Mayor on Crossrail and the construction of the London Olympics.

The consultancy is being investigated by TfL's auditors KPMG on behalf of the official watchdog, the Audit Commission.

Mr Kiley has received £416,250 of the £737,500 he could have earned as a consultant. Mr Livingstone said: "Bob is not well enough to provide advice. If he recovers we would love to have his advice. Let's just wish him God speed to recovery."
