Donald Trump's campaign has filed a complaint with the Federal Election Commission accusing the UK's Labour Party of illegal foreign interference in the US presidential election. The complaint alleges that Labour facilitated British activists to volunteer in key battleground states, which Trump’s campaign argues constitutes illegal foreign contributions. Labour leader Sir Keir Starmer defended the actions, stating that party members are volunteering in a personal capacity, a practice consistent with past elections. The Labour Party has not officially responded to these allegations, while the complaint has sparked backlash from Republicans and some UK politicians. The accusations, if proven, could lead to significant legal repercussions given the strict regulations on foreign involvement in US elections. The FEC will review the complaint as part of its oversight duties.
