Will HS2 'heal north/south divide'?
Details of the next phase of the £32bn HS2 high-speed rail network have been unveiled by the government.
The preferred route of phase two, running northwards from Birmingham will have five stops at: Manchester; Manchester Airport; Toton in the East Midlands; Sheffield; and Leeds.
Chancellor George Osborne said it was "the engine for growth in the North and the Midlands of this country".
Phase one's London-Birmingham link has faced considerable opposition.
Professor John Tomaney, from the School of Planning at UCL, told the Today programme's Evan Davis that "There's very little evidence that building a high-speed rail line heals the north/south divide".
Sir Richard Leese, chair of Manchester City Council, argued that HS2 "doesn't guarantee growth but it gives us a better chance."
