Labour's international trade spokesperson Barry Gardiner has said Diane Abbott has a serious long-term illness and replacement Lyn Brown is a feisty, admirable, plucky woman.
Abbott has stood down as shadow home secretary due to ill health and Labour's shadow minister for policing, Lyn Brown, will be taking over.
Gardiner told Julia Hartley-Brewer: "Let me say that I think Diane is clearly not well, and I understand that it’s a condition which has been diagnosed and is long-term and I think anybody who’s seen her in the past couple of weeks would realise that she was showing that she was not well.
"I hope she’s getting appropriate treatment and that she’s feeling better.
"I’m not prepared to make any further judgements outside of what I know."
He also commented on Brown, as Julia mentioned an incident where she barged into a blind man and had to apologise for it.
Gardiner said: "I’ve known Lyn for many years, I’m very proud to serve with her because she’s been an admirable MP and she’s served her constituents absolutely superbly.
"I know nobody who fights harder for people and in particular for people who are at the bottom of the pile in our society than Lyn Brown.
"If you listen to any of the things she has said and see the work she has done, she is one of the most feisty, admirable, plucky women that I know."
