The project to bring high speed rail services to Yorkshire has around a £3 billion funding gap according to the National Audit Office.
The controversial new HS2 link will cut the journey time from Leeds to London to just an hour and 20 minutes and is due to be completed by 2033. The government spending watchdog says Ministers have yet to decide where three-point-three billion pounds worth of funding for the project is coming from.
Geraldine Barker from the National Audit Office and Rail Minister Simon Burns say the project is still in the early stages.
