The rise in transport fares in the capital will come into effect more than two weeks later than planned following a "farcical" failure of communication, it is claimed.

Season tickets on travelcards are set to go up by 4.1 per cent, but the fares were capped at retail price index of 3.1 per cent by Chancellor George Osbourne.

The delay in putting up fares could cost £14m in lost revenue and was caused by a lack of communication between Mayor Boris Johnson and the Exchequer, according to London Assembly member John Biggs.

The rise was due to come into effect on January 3, but now Transport for London is said to be working towards implementation on January 19.

John Biggs, chair of Budget Monitoring Sub-Committee, said: "It is farcical that what appears to be a lack of communication between the Chancellor and the Mayor has resulted in TfL being unable to implement the planned fare rises.

"While this will bring a few weeks relief to Londoners in the new year, it will leave a hole in TfL's budget, one which the Mayor said fares needed to increase to fill."
