How would Andy Burnham govern as Prime Minister?
Sarah talks to Andy Burnham's close friend and political ally, Steve Rotheram.
Andy Burnham has set out his vision for the country should he become Prime Minister.
It includes setting up a 'No10 North' in Manchester and delivering the biggest programme of council house building in the post-war period, but because of his strange route to the doorstep of power we don't actually know much about how it all might work.
Steve Rotherham is a friend of Andy Burnham and the mayor of Liverpool City Region. He also co-wrote his book, 'Head North: A Rallying Cry for a More Equal Britain', the closest thing we have to an Andy Burnham manifesto.
Radio 4's Sarah Montague talks to the Liverpool Metro Mayor, to find out what an Andy Burnham government might actually look like.
