Diane Abbot says she entered the Labour leadership race to encourage the "broadest possible debate" and said she was confident she can get the 30 nominations needed.
"Every wing of the party should be involved in the debate," she said. "What we had before I intervened was front runners who were all very nice, but were a little similar."
"It is my aim to have the broadest possible debate. All the other candidates have been saying we want every voice to be heard and I'm just making that real."
