- The move followed UK political news that Andy Burnham won a by-election, a catalyst unrelated to Brazil that coincided with a 2.0-point uptick for Lula.

Veteran UK Labour politician Andy Burnham won the Makerfield by-election on Friday, securing a parliamentary seat and clearing the way for a widely expected leadership challenge against Prime Minister Keir Starmer. Burnham, 56, has served as Greater Manchester mayor since 2017 and returned to parliament after easily beating the Reform UK candidate in the northwest England constituency. In his acceptance speech, he said he had secured nearly 55% of the vote and won by more than 9,000 ballots. The contest was triggered by the resignation of Labour MP John Simons, and the seat’s electorate of roughly 77,000 people delivered turnout of 59%, the highest for a by-election in seven years. Starmer, in office since July 2024, has faced calls to quit from dozens of Labour MPs amid resignations and sliding poll numbers, while Burnham has signaled he intends to challenge for the party leadership and the premiership.
