Labour's John Mann, chair of the All-Party Inquiry into Antisemitism, has retained his seat in Bassetlaw, north Nottinghamshire, with a 8,977 majority over Tory Keith Girling.
"I'm really pleased to see the result being a high swing to Labour which is totally contrary to what's happening elsewhere in the country," Mr Mann said. "I'm looking forward to getting back to work tomorrow and fighting the cause for the people of Bassetlaw."
His Labour colleague Denis MacShane, chair of the Antisemitism Inquiry panel, also retained his seat in Rotherham.
An outspoken campaigner against antisemitism and anti-Zionism, he was the target of a controversial campaign by Muslim group MPAC which sent election leaflets highlighting his voting record and repeating tabloid stories about his expenses claims. He alleged that one MPAC activist had been urging people to vote BNP in Rotherham.
