Labour Party's Keir Starmer is expected to win a historic majority of 194 seats. With a central projection of 422 Labour wins, this would beat Tony Blair's 1997 landslide victory of 179 seats, according to YouGov. It would additionally be the second-largest majority in UK political history after Stanley Baldwin’s 210 seats in 1924.

The YouGov poll demonstrates that Labour is expected to win 422 seats out of 650 in the UK Parliament in this year's general elections, while the current ruling party, the Conservative Party, will garner only 140 seats.

In the last elections in 2019, Labour only acquired 222 seats – the biggest number of seats Labor has ever won and the largest majority the UK has seen in the past 100 years.

The Tories are anticipated to garner only 140 seats – a plunge of 232 seats compared to the 372 seats it currently has – marking the lowest number for them since 1906.

Labour leader Keir Starmer is expected to lead the UK next month if the numbers prove right.

'Bring back optimism'

Prime Minister Rishi Sunak announced, on May 22, that a national election will take place in the second half of this year. "Spoiler alert: there is going to be a general election in the second half of this year," Sunak told Parliament.

Labour's Sadiq Khan clinched an unprecedented third term as London's mayor on May 5, leading his party to victory in a series of mayoral and local elections, dealing a significant blow to the ruling Conservatives ahead of an anticipated general election.

Khan, aged 53, defeated Conservative opponent Susan Hall by an 11-point margin, dashing largely dim hopes among Tories of wresting control of the UK capital from Labour for the first time since 2016.

Labour, who has been out of power since 2010 and suffered a heavy defeat by Boris Johnson's Conservatives in the last general election in 2019, also decisively won a parliamentary seat from the Tories.

It is worth mentioning that former Tory MP Mark Logan announced his support for Labour in the upcoming general election last month, expressing his belief that the party can "bring back optimism into British life."

Logan, who represented Bolton North East for the Tories until Parliament dissolved, stated, in an exclusive interview for BBC News, that Labour had undergone a "journey" and now embodied "centrist politics".

He also remarked that the Tory Party had become "unrecognizable" compared to the one he joined a decade ago.
