Union claims cost will be reached if consortium remains in administration until April

The collapse of the Metronet consortium will cost tax players 拢500m, according to tube union RMT.

A report by the union claims that the cost will be reached if the consortium remains in administration until April.

The report comes the day before the House of Commons transport committee will publish what is expected to be a critical report of Metronet and the part privatisation of the London underground.
