Andy Burnham has used his first major policy speech as Labour leadership frontrunner to promise the biggest shake-up of political power in modern British history, pledging to hand sweeping new authority to local leaders and relocate part of the prime minister's office to Manchester.
Speaking at the People's History Museum in the city where he spent nine years as mayor, Burnham laid out a 10-year plan to revive a UK economy he described as stuck in a rut since the 2008 financial crash.
