HS2 rail project 'could cost taxpayer £80bn'

The HS2 high-speed rail project could cost more than £80bn - almost double the current estimated cost of £42.6bn, a free-market think tank has said.

The Institute for Economic Affairs (IEA) expects lobbying by local councils for extra infrastructure and design changes will inflate the cost.

It wants HS2 to be scrapped and the money spent on other transport schemes.
