Sir Keir Starmer was repeatedly asked whether Ms Abbott, the shadow home secretary, would show up later as MPs vote on giving Theresa May the power to trigger the start of Britain’s divorce talks with the European Union.
Last week Ms Abbott failed to turn up for a vote on the Article 50 bill, claiming illness despite speaking in Parliament hours before.
Sky News’ Sarah-Jane Mee asked Sir Keir: “There is Diane Abbott, do you know if she is going to turn up today?”
Clearly unwilling to engage in the line of questioning, the MP for Holborn and St Pancras replied: “I can only speak for myself and I am not going to attempt to speak for anybody else…”

Interrupting, Mee said: “You are all part of the party you all speak to each other!
“Diane Abbott it is quite embarrassing, she says she was ill and that was why she didn’t turn up to the last vote.
“You have got #BrexitFlue #prayforDiane, it looks really bad that one of your senior MPs doesn’t turn up for a vote when she was seen in a pub the night before!”
Again, Sir Keir said he could not speak for others, causing an exasperated Mee to say: “I am trying to help you here, you must have spoken to her.
“Labour is coming out of this quite badly.”

In reply, Sir Keir said: “From the outset we have said we accept the result of the referendum and that means the Prime Minister must be allowed to start the negotiations [with the EU].
“We have been concentrating on putting in scrutiny and accountability.”
He also promised Labour will continue to push for tariff-free access to the single market and to protect workers’ rights.
Asked if Ms Abbott, or other Brexit rebels, would face having to resign, Sir Keir again refused to speculate on what retribution those who ignore the Labour whip would face.
“You keep asking me to account for Diane Abbott’s actions and I am not going to do so,” he snapped.
“It is up to Diane Abbott what she does.”
