In the biggest upheaval the Labour party has seen for more than 20 years, leadership frontrunner Jeremy Corbyn - who fought from the start as an outsider - has turned the party's politics on its head.
His socialist appeal has seen a record number of members sign up to vote, with young and old like seemingly reinvigorated by his policies and vision for the party.
But a Labour party candidate has claimed that if Corbyn becomes leader, would-be MPs like could face being deselected because of their more moderate views.
Rachel Burgin, who stood as a Labour candidate for Hitchin and Harpenden at the last election, says that she now finds herself abused online by people claiming to be Corbyn supporters, who accuse her of being a Tory.
The initial response is [to be upset], but if it was just upset you can get over that. There is something bigger, and the Labour party has to be a broad church... we have to be a party that brings people in, not drives people away.
However, dedicated campaigners that spoke to Libby Wiener in Salford say they believe Corbyn is the man to unite, rather than divide the party.
