London: One year after his election, Jeremy Corbyn is leading the most unpopular opposition Labour Party in British history, according to an analysis of polls published Monday.

Labour is currently trailing the ruling Conservatives by an average of 11 points, according to the Nuffield series of British General Election studies.

No Labour Party has faced such a deficit 12 months after electing a new leader since modern polling began in the 1950s, according to a Press Association analysis of historic polls to mark the anniversary.

It is also the second-worst polling level for any major British opposition party since the Second World War, behind the 25-point deficit suffered by William Hague’s Conservatives in 1998, when Labour Prime Minister Tony Blair was riding high.

Veteran leftist Corbyn, 67, is currently embroiled in another leadership campaign after being challenged by MP Owen Smith, but looks set to keep his job thanks to the consistent support he enjoys among grass roots members and trade unions.

However, he is unpopular with his own MPs, around 80 per cent of whom voted against him in a recent vote of no confidence.

Corbyn loyalist and shadow finance minister John McDonnell admitted Monday that the current leadership team needed to improve its performance.

In an interview with the BBC, McDonnell blamed the bad figures on discord within the party caused by rebel MPs.

Labour had a turbulent weekend, with prominent donor Michael Foster being suspended after comparing Corbyn’s allies to Nazi storm troopers in a newspaper article.

Shadow foreign minister Emily Thornberry also sparked a row after accusing a television presenter of sexism when he asked her the name of the French foreign minister, which she did not know.
