David Cameron: HS2 is 'vital for Britain'

Details of the next phase of the £32bn HS2 high-speed rail network have been unveiled by the government.

Prime Minister David Cameron said the scheme was "vital for Britain if we're going to succeed in the global race".

The preferred route of phase two goes from Birmingham northward along two branches: to Manchester Airport and Manchester; and via Toton near Nottingham, to Sheffield and Leeds.
