The first poll for the Makerfield by-election has revealed a tight contest between Greater Manchester Mayor Andy Burnham and Reform UK, with Burnham holding 43% support compared to Reform's 40%.

The polling results have prompted Reform UK leader Nigel Farage to call for right-wing voters to unite behind his party's candidate ahead of the June 18 election. Farage has framed the contest as a two-horse race between his party and Burnham.

Meanwhile, the Green Party is facing internal pressure regarding their participation in the by-election. Party politicians and activists, including a former leader, have reportedly urged Green candidate Zack Polanski to consider standing aside to support Burnham's candidacy.

The calls for Polanski to withdraw reflect concerns within Green Party circles that splitting the vote could impact the election outcome. These discussions highlight the strategic calculations parties are making in what appears to be a closely contested race.

The Makerfield constituency by-election was triggered following the previous MP's departure, setting up what polling suggests will be a competitive contest between the main candidates on June 18.
