The news that the construction of certain sections of HS2 will be delayed to save money has been described as "potentially a real body blow for the UK’s economic recovery".
The BBC first reported that the government's cuts will primarily affect the high-speed railway between Birmingham and Crewe, and between Crewe and Manchester.
Phase One of HS2 involves the railway being built between London and Birmingham, with the line extended from the West Midlands to Crewe in Phase 2a.
