A businesswoman embroiled in a £1.6 billion High Court battle with Barclays was referred to as a "dolly bird" and a "tart" by former bank chiefs, a judge has heard.

The terms used by two then Barclays bosses to describe Amanda Staveley, in a telephone call during the financial crisis 12 years ago, emerged at a High Court trial on Thursday.

Ms Staveley is speaheading the proposed takeover of Newcastle United, with backing from Saudi Arabia's Public Investment Fund and the Reuben brothers.

Richard Boath referred to Ms Staveley as "that dolly bird" during an evening call with Roger Jenkins in October 2008.

Mr Jenkins referred to her as "the tart".

Ms Staveley, 47, has made complaints about the behaviour of Barclays bosses when negotiating investment deals during the 2008 crisis 12 years ago.

She says Barclays agreed to provide an unsecured £2 billion loan to Qatari investors, but the loan was "concealed" from the market, shareholders and PCP Capital Partners, a private equity firm she runs.

PCP is suing the bank and wants £1.6 billion in damages.

Mr Justice Waksman began overseeing a trial on June 8. It is due to end in August.

Lawyers representing PCP had referred to the telephone conversation between Mr Boath and Ms Staveley early in the trial.

The detail of words used emerged on Thursday, when Mr Jenkins, who was Barclays' executive chairman of Middle East business in October 2008, began giving evidence and a transcript of the call was made available to journalists.

Mr Justice Waksman has already heard evidence from Ms Staveley and witnesses called by PCP.

Ms Staveley says PCP introduced Manchester City owner Sheikh Mansour to Barclays and he "subscribed" to invest £3.25 billion.

She says PCP is owed money for the work it did. Barclays disputes PCP's claim and says it is made "of sand".

Mr Boath had said, during the October 2008 call, “Yes. Now, that dolly-bird that represents – is it – what’s her name?” the transcript showed.

Mr Jenkins had replied: “Amanda Staveley.”

Later in the call, Mr Jenkins had said: “Well I am – you know, I’m going to call the tart; I was going to call the tart.”

Mr Boath had asked: “Who’s the tart?”

Mr Jenkins had replied: “Amanda.”
