A Labour MP has denied changing the lyrics of the Beatles song Hey Jude to "Hey Jews" while singing on a coach back from Cheltenham races.
Dan Carden, Shadow International Development Secretary, allegedly sang the offensive lyrics on a "raucous" return journey from the festival in March 2018.
The 33-year-old ally of Jeremy Corbyn has served as Member of Parliament for Liverpool Walton since 2017.
It is the latest saga in Labour's ongoing anti-Semitism scandal which has seen Corbyn accused of allowing a culture of bigotry to grow in the party.
Carden's colleague, Labour MP for St Helens North Conor McGinn, is accused of repeatedly calling a colleague "p**f" while on the coach trip in 2018.
The alleged incident happened late on March 15, 2018, Buzzfeed News reports.
There were other MPs from different parties on board as well as Labour MPs, the website alleges.
As he and other Labour politicians played music from their phones throughout the two-and-a-half-hour coach trip, Carden is believed to have repeatedly sung the chorus as "Hey Jews".
Responding to the allegations on Twitter, Carden wrote: "I have been categorical in my denial about allegations relating to a coach trip some twenty months ago.
"This was a coach full of journalists and MPs. If anyone genuinely believed any anti-Semitic behaviour had taken place, they would've had a moral responsibility to report it immediately.
"Yet this allegation is only made now when a General Election is imminent.
"I stand by my record as an anti-racist campaigner. I would never be part of any behaviour that undermines my commitment to fighting racism in all its forms."
Daily Star Online has approached Conor McGinn for comment.
General Election: Who will you vote for?
7000+ VOTES SO FAR
A spokesman for the MP said: "Conor's record as a staunch supporter of the LGBT community speaks for itself.
"As an MP he led the campaign which delivered a monumental and historic change in the law to finally extend equal marriage to the whole of the UK."
The revelations come just a month before Brits are due to go to the polls again in the country's third general election in less than five years.
Conservative Party leader Boris Johnson is favourite to win, with polls from YouGov today suggesting Labour's vote is "collapsing in the North" under pressure from both the Brexit Party and the Lib Dems.
