UK's Labour set to win huge majority in parliamentary elections: Exit polls

British Prime Minister Rishi Sunak may be on course for a bruising defeat with his Labour Party rival Keir Starmer set for a landslide win, according to the definitive election night exit poll released on Thursday as polling stations across the country closed in the landmark UK general election.

According to the exit poll, which is often quite close to the final tally, Labour could win as many as 410 seats, comfortably crossing the halfway 326 mark and notching up a 170-seat majority with the incumbent Tories down to just 131 seats.

Sunak's future as leader of the Conservative Party now hangs in the balance, hours after the British Indian leader and the man who wants his job -- Starmer -- were among the first few voters to cast their votes along with millions in England, Scotland, Wales and Northern Ireland.

Sunak and his wife Akshata Murty walked hand-in-hand to their local polling booth on a sunny day in his constituency of Richmond and Northallerton in Yorkshire, northern England
