Green energy entrepreneur Dale Vince was invited to Downing Street to help welcome Andy Burnham as the new Prime Minister, marking Burnham's first day in office after Keir Starmer's resignation. Vince, known for his outspoken environmental and political views, used the occasion to publicly caution Burnham against appointing Ed Miliband as Chancellor, calling such a move a "mistake" — a comment that highlights early tensions within Labour over the shape of the new Cabinet.

Vince attended the event wearing a t-shirt bearing the slogan "chips are vegan", consistent with his long-standing public persona as a vegan and clean-energy advocate. His warning comes as Burnham prepares to unveil his Cabinet, with speculation swirling over whether Miliband will be handed the Chancellorship, and follows Burnham's own first speech as PM in which he pledged to "be better" than his predecessor while hinting at a leftward shift in policy direction, though without giving firm details.
