Treasury Chief Secretary Danny Alexander has told He told the BBC's Andrew Marr Show he is "very confident" that the Government will be able to complete the HS2 project for less than the allocated budget of £42.6 billion.
The real cost is the budget we set out in June this year, £42.6 billion. It hasn't changed at all and that number includes within it a significant amount of contingency.
I'm very confident that as we work through the project and deliver it we'll not just deliver it within that budget but like the Olympic stadium project, under-budget too.
