UK Bond Traders Watch Makerfield By-Election Amid Concerns Over Potential Leadership Challenge

The Makerfield by-election, scheduled for June 18, has become one of the most politically charged contests in recent British history, with former Greater Manchester Mayor Andy Burnham standing as the Labour candidate in a seat once considered unwinnable. Polls, including a leaked survey reported by The Telegraph, now suggest Burnham is favoured to win, partly aided by a split on the right between Reform UK and the smaller Restore Britain party. Hundreds of Labour MPs and activists have descended on the constituency, with canvassers briefed to campaign under Burnham's personal brand rather than the Labour Party label, reflecting the degree to which the contest has become a vehicle for his leadership ambitions. Inside Westminster, Starmer's position appears increasingly fragile following the resignation of Defence Secretary John Healey, and MPs on the ground in Makerfield are openly discussing a Burnham challenge as a near-certainty should he win. Bond markets are also watching closely: investors at BNP Paribas Asset Management, Neuberger Berman, and Allspring Global Investments warn that a Burnham victory could trigger gilt volatility, given uncertainty about his fiscal plans and his past dismissive comments about bond markets. The campaign's ground operation is led by a core group of female political operators including Louise Haigh and Anneliese Midgley, who have replaced Starmer's former inner circle as the dominant power brokers. Burnham's team is targeting roughly 16,000 undecided voters, though strategists remain cautious about the threat posed by habitual non-voters who turned out heavily for Reform in recent local elections.
