Sir Julian Lewis: Normally when functions and roles are devolved from London to another area, we see a diminution in the capital and an increase in the area concerned. There is an obvious danger of duplication by having a No. 10 North and a No. 10 South, so will the First Secretary, whom I congratulate on her appointment, be transparent about this and agree that the public should be able to see how many people are working permanently in No. 10 North, how many are working permanently in No. 10 South, and how many are going back and forth between the two?

[The First Secretary of State (Louise Haigh): The right hon. Gentleman is right that traditionally the model of moving people or roles out of London has meant duplication in the centre. That is exactly what we are attempting to fix. We want new senior roles across the country. I pay tribute to the former Prime Minister, the right hon. Member for Richmond and Northallerton (Rishi Sunak), who created the Darlington campus. That campus is a proper model of delivery, with senior policy making and civil servants in Darlington, based around the Treasury there. It has helped to deliver and change decision making, and that is exactly what No. 10 North is attempting to do.]
