Nigel Farage's Reform UK has made big gains in English local elections, cementing it as a prime challenger to Britain's traditional main parties. It has won over 630 council seats from around 1,500 declared so far, with results from a further 100 or so still to come in.

Britain’s two main parties suffered significant losses in municipal and mayoral votes as Reform U.K., a right-wing populist party, surged ahead.

Both Labour and the main opposition Conservative Party braced for losses in the midterm poll. The hard-right Reform UK led by Nigel Farage fielded more candidates than any other party and hoped to make major gains in the elections that are deciding 1,600 seats on 23 local councils, six mayoralties and one seat in Parliament.
