Angela Rayner will tell leaders in the north of England that she will help them “break” the system that “hoards power and investment” away from them in a speech on Friday.
The Deputy Prime Minister will call her English Devolution programme the “biggest power shift in a generation” at the annual Convention of the North event, being held this year in Preston.
Ms Rayner, who is also Local Government Secretary, is also expected to outline plans for more building in the North.
“You’re being resisted by a system that hoards power and investment away from where it needs to be.
The Government is re-organising local authorities and bringing in new mayoral powers under its devolution plans.
