A representative of the Momentum campaign group has said Jeremy Corbyn's opponents within the Labour Party represent "a small minority."
Santiago Bell-Bradford was speaking to talkRADIO on the final day of voting in the Labour leadership contest, which was triggered when MPs passed a motion of no confidence in Mr Corbyn.
The Labour leader has also faced opposition from a movement called Labour Tomorrow, founded by Gordon Brown's former aide Nicola Murphy. The movement, which has raised a reported £335,000, has donated significant sums of money to groups opposing Mr Corbyn.
However Bell-Bradford played down talk of a possible split in the Labour Party, telling Sam Delaney "I don't think it's likely [to break apart] and I hope it isn't true.
"When you look at what we've achieved over the last year under Jeremy, lots of those achievements have also come with the help of the whole party.
"It's a very small minority of people who are making this abuse," he added. "There's one thing we can all unite against and that's the Tories.
"I think this campaign has shown how effective we can be at campaigning. It's almost been a test of how to run in a general election. We had a two-candidate race, and both of them put forward very left-wing progressive policies."
