The Chancellor George Osborne's called it a ''massive moment'' for the North of England

He's talking about plans unveiled today for Greater Manchester to have its own elected mayor and to have greater control of how money is spent in the area on things like transport, housing and policing.

It's part of the Government's aim of creating a so-called Northern Powerhouse to rival the economic and political power of London. But critics say creating a mayor will actually take decision-making further away from the people.
