The nickname also reflects Burnham's deep roots in northern England.
Born in Merseyside in January 1970, he grew up between Liverpool and Manchester. He joined the Labour Party as a teenager before studying at Cambridge University.
He became the Member of Parliament for Leigh in 2001 and remained the area's MP for 16 years. During that time, he served in several senior government roles, including Chief Secretary to the Treasury, Culture Secretary and Health Secretary under former Prime Minister Gordon Brown.
Despite having opportunities to continue his career in Westminster, Burnham chose a different path in 2017 by becoming the first directly elected Mayor of Greater Manchester.
That decision strengthened his image as a politician focused on local communities rather than national political battles.
How the Mayor's Role Changed His Image
Becoming Mayor of Greater Manchester transformed Burnham's public profile.
Instead of being seen simply as another Westminster politician, he became closely associated with transport, housing, policing, healthcare and regional investment across Greater Manchester.
He also pushed for greater powers and funding for English regions, arguing that decisions affecting northern communities should not always be controlled from London.
This approach helped him build support well beyond Labour voters.
