'Still standing!' Diane Abbott responds after being temporarily replaced as shadow home secretary due to 'ill health'

Diane Abbott has said she is “still standing” and hopes to return to the political front line soon, after Jeremy Corbyn appointed a Labour colleague to fill in as shadow home secretary while she is off work due to illness.

Ms Abbott pulled out of two high-profile General Election events on Tuesday and Mr Corbyn announced on the eve of polling that shadow home affairs spokeswoman Lyn Brown is to stand in for her.

Shadow cabinet colleague Barry Gardiner said she had been diagnosed with a long-term condition which may have played a part in below-par interview performances during the election campaign.

There was no immediate response from Ms Abbott’s office and the Labour Party declined to discuss details of her condition.

But in a cheery message on Twitter, Ms Abbott broke her silence to say: “Touched by all the messages of support. Still standing! Will rejoin the fray soon. Vote Labour!”

It is understood that the condition affecting the 63-year-old MP for Hackney North and Stoke Newington would not prevent her eventual return to work once she has recovered.

Close Corbyn ally Ms Abbott has come under relentless fire from Conservatives following an interview with LBC radio in which she forgot figures for Labour’s police funding plans and an appearance on Sky News when she struggled to discuss details of a security report.

She was replaced by shadow foreign secretary Emily Thornberry for a debate on BBC Radio 4’s Woman’s Hour and a hustings organised by the London Evening Standard on Tuesday.

Mr Corbyn on Wednesday asked Ms Brown is to stand in for her during her period of ill-health.

West Ham MP Ms Brown was among a number of shadow ministers who quit the front bench last year, saying that Labour needed a new leader “for the good of the party and the country”. However, she returned to Ms Abbott’s home affairs team three months later as shadow minister for policing.

Mr Gardiner said he had been told by party officials that the shadow home secretary was suffering from a long-term illness.

“Diane is clearly not well and I understand that it is a condition which has been diagnosed and is long-term,” the shadow international trade secretary told TalkRadio presenter Julia Hartley-Brewer.

“I think anybody who has seen her in the past couple of weeks would realise that she was showing that she was not well, in the way in which she had been operating.

“Everybody is aware that Diane didn’t perform well in a couple of programmes, but what we didn’t know was why and I think that has now become clear.”

He added: “I am sorry for her, obviously, that she has got this condition and clearly it is now a matter for her to get properly diagnosed and properly treated and I wish her well in her recovery.”

Mr Gardiner later declined to confirm his comments to the Press Association, saying it was a matter for Ms Abbott to decide what details should be made public.

Shortly before announcing Ms Brown’s temporary appointment, Mr Corbyn told BBC Breakfast that Ms Abbott had not been well for a “couple of days” and was “taking a break from the campaign”.

He said: “Of course Diane is somebody that works extremely hard and represents her community very well, and I have to say has received totally unfair levels of attack and abuse, not just recently – over many years.”

Prime Minister Theresa May said: “How Jeremy Corbyn manages his shadow cabinet is for him. I just wish Diane a speedy recovery.”

Ms Brown, 57, was appointed to Labour’s shadow home affairs team when Mr Corbyn named his first frontbench team in 2015.

MP for West Ham since 2005, she is fighting Thursday’s election in the ultra-safe east London seat, which she held with a majority of almost 28,000 in 2015.

She was a Labour whip under Gordon Brown and Ed Miliband, before being appointed shadow minister for communities and local government in 2013 and then shadow home office minister two years later.
