This is the announcement from the BBC news site which has just been made.
Diane Abbott has gained enough nominations to get onto the Labour leadership ballot paper.
The backbencher managed to reach the threshold after fellow left-winger John McDonnell withdrew from the race.
Ms Abbott wil go up against four former cabinet ministers - Ed Balls, Andy Burnham and David and Ed Miliband.
Labour members and trade unionists and MPs will now be balloted and the result announced on 25 September.
