The Greater Manchester mayoralty made Andy Burnham famous. Now he's hoping he can take the approach he developed in the city to the whole country.

This week on Westminster Insider, host Sascha O'Sullivan speaks to four serving mayors — and one former one about whether the role will prepare Burnham for the highest office in the land.

Labour Mayor of the East Midlands Claire Ward, who was a minister in Gordon Brown's government, told Sascha that mayors have much more power than junior minister.

Oliver Coppard, the Labour Mayor of South Yorkshire, explains how the job requires you to manage different competing interests, albeit on a smaller scale than as a prime minister.

But former Mayor of the West Midlands Andy Street warns that when it comes to financial responsibility and party management — two pitfalls of Keir Starmer's leadership — the job of mayor is "totally different".

Helen Godwin, West of England Mayor, and Kim McGuinness, Mayor of the North East, have graciously said they won't kick Burnham out of the Labour mayors' WhatsApp group if he becomes PM.
