Labour has seen a minimal increase in poll support since Keir Starmer announced his resignation, with Andy Burnham emerging as the likely successor. A recent YouGov survey shows Labour's support at 20%, a two-percentage-point rise that falls within the margin of error.

The same poll indicates that Labour trails Reform UK by four points, with Nigel Farage's party polling at 24%, down one point from the previous survey. The Conservative Party remains unchanged at 20%, while the Green Party and the Liberal Democrats are both at 13%, down two and one points respectively. The Green Party's current figures represent their lowest since October and an eight-point drop from their March peak.

Despite the marginal gains, the combined support for Labour and the Conservatives has reached 40%, the highest for the two traditional main parties since July of the previous year. Starmer announced his decision to resign last week, following Burnham's victory in the Makerfield by-election.

Burnham, the former Greater Manchester mayor, is now considered highly likely to replace Starmer as Prime Minister, potentially taking office on July 20 if no other Labour leadership contenders emerge. In his first major address since Starmer's announcement, Burnham outlined plans to establish a new Downing Street operation in Manchester, intended to be the central hub of a "rewired Britain." He also pledged to initiate the most extensive council house building program since the post-war era and to grant regions greater public control over essential services such as water, energy, and transport.

Burnham described these proposals as leading to the "biggest rebalancing of power our country has seen," aiming to overcome resistance from Whitehall. "The days of Whitehall fighting the devolution of power into the regions and nations are over for good," he stated. He also sought to reassure markets regarding fiscal policy, promising that his initiatives would be funded through "stability that comes from sound public finances" and adherence to "the discipline of our current fiscal rules." However, he acknowledged that taxpayer support would be necessary to address the cost-of-living challenges faced by households.

The YouGov survey included 2,437 British adults and was conducted between June 28 and June 29.
