While allies of the Labour leader have insisted he notified his deputy of the impending reshuffle, her aides are said to have maintained that she had been excluded from the detailed discussions and “knew nothing about it.”

One aide is also said to have challenged Sir Keir’s team on a private Whatsapp group used by Labour special advisers, stating that they should have been alerted to the reshuffle in advance.

Asked about the controversy on Tuesday, Ms Nandy said: “I have not spoken to Angela since the reshuffle was announced. I have been too busy getting a team together and putting a plan together.

“I have been through a lot of reshuffles over the past 11 years. I think that the leader makes the decisions, the gaffer picks the team, that’s how it goes and that’s how it has always gone.

“Frankly, I couldn’t care less about the circus of who’s in and who’s out, who’s up, who’s down, who knew, who didn’t.”
