The Hackney North and Stoke Newington MP lost the whip in April last year after writing a letter to The Observer suggesting Jewish, Irish and Traveller people are not subject to racism âall their livesâ.
While she remains a party member, she has sat as an independent MP while an internal investigation of her comments continues.
The row over alleged racist comments by major Conservative donor Frank Hester â that she made him want to âhate all black womenâ and âshould be shotâ â has brought renewed calls for the whip to be returned to Britainâs first black female MP.
While Sir Keir Starmer said Ms Abbott should receive âsupportâ in relation to the abuse she receives, he has resisted calls to return the whip.
On Thursday, he said her suspension from the Parliamentary Labour Party was âan entirely different issueâ and subject to an independent process that was separate from him.
But at a lunch with Westminster reporters, his deputy Angela Rayner said she would like Ms Abbott to be reinstated as a Labour MP.
She said: âPersonally, I would like to see Diane back but the Labour Party has to follow its procedures.

âAnd for me, that is the most important thing, that we have made sure our party is fit to govern by making sure we have got complaint procedures that are robust and people can have confidence in.â
She also expressed âfrustrationâ with the length of time the internal investigation had taken.
Other senior Labour figures have been less willing to express an opinion. Yvette Cooper, appearing on LBCâs Tonight With Andrew Marr, said she could not comment on the independent process.
But some backbenchers have been more outspoken. Apsana Begum, MP for Poplar and Limehouse, told the BBCâs Newsnight that Ms Abbott should âabsolutelyâ have the whip restored.
She said: âDiane Abbott is a trailblazer. She is one of the strongest and most powerful advocates for the British black community. She is a hero of the anti-racist struggle.
âAll of this needs to be recognised. She has had a tremendous parliamentary career to date and she should have the whip restored.â
