UK Labour Party loses long-held seat to Greens in by-election

The UK's Labour Party, led by Prime Minister Keir Starmer, has lost a parliamentary seat in Greater Manchester to the Green Party in a by-election. The seat had been held by Labour for about a century, making the defeat a significant political setback.

The result is seen as an embarrassing blow to Starmer and his party, putting pressure on the Prime Minister. The Greens' victory is described as an upset in a normally safe Labour area.
