Devolution in the UK: What could change?

This week the government is inviting hundreds of experts and business leaders from the North of England to a devolution 'policy' summit in Leeds.

The conference is expected to generate a plan to devolve some powers away from Westminster to Leeds, Sheffield and Manchester.
