Nigel Farage revealed NatWest staff suggested he was a Russian spy in bombshell internal messages.
The GB News presenter has been at the centre of a debanking scandal after his account with Coutts, which is owned by NatWest Group, was closed earlier this year over his political views.
Mr Farage used a subject access request to obtain all the information NatWest holds on him.
In the messages, one member of staff said: “He got paid from the Kremlin, bet he’s a spy.”
It comes after he revealed a further raft of messages on Monday with staff crowing about having potentially “single-handedly driven NF out of the country”.
They said: “Have you all seen Nigel Farage’s Twitter? No one will bank him now. Have we single-handedly driven NF out of the country?”
Another said they would “throw a milkshake at him if I was approached to open an account for him” in reference to a similar previous incident when he was on the campaign trail.
In further messages, staff said they “hope that knocked him down a peg or two” and asked “what’s the crackpot saying now”.
Mr Farage is branded an “awful human being” in another exchange.
An employee also says Mr Farage is “Mr nobody now he has completed Brexit”.
A NatWest Group spokesman said: “We have written to Mr Farage to apologise sincerely for the deeply inappropriate comments made about him and the poor behaviours displayed.
“Neither are consistent with the standards of service that our clients should expect.
“The Group has commissioned an independent review into recent events, phase one of which has been delivered to the board and we will complete the necessary processes and publish the key findings, along with the group’s response, as soon as possible.
“We are determined to learn the necessary lessons from this so that in the future we live up to the high expectations our clients rightly place upon us.”
