Andy Burnham: profile of the new UK Prime Minister

Andy Burnham was previously mayor of Greater Manchester. An advocate for decentralization, he has also campaigned for measures to address the cost of living.

Starmer's departure

Keir Starmer announced on July 17, 2026 his withdrawal by September, after roughly two years in power. His popularity collapsed with particular speed and severity — among the most pronounced for any UK Prime Minister — with his hesitant leadership style and the country's difficult circumstances cited as principal causes.

Under his leadership, Labour lost constituencies to Reform UK — formerly the Brexit Party, a British far-right, populist and national-conservative party — led by Nigel Farage.

During the week of July 14, 2026, Starmer travelled to Kyiv, then to Paris, where Emmanuel Macron presented him with the Legion of Honour — France's highest national decoration, established in 1802 by Napoleon Bonaparte to reward distinguished service to the nation.

In an interview with Sky News published that week, Starmer stated he could be remembered as the one who "saved the Labour party" following the Jeremy Corbyn era, and that he would leave office with pride.
