Baroness Mone of Mayfair claimed almost £4,000 in expenses in the first two months after she was awarded a peerage by David Cameron.

Aides said that she had given every penny away to charity, including an extra £1,000.

They declined to name the organisations involved, saying that they would be announced on a yearly basis.

Shortly before she became a peer Lady Mone suggested that she did not need money from the public purse and that she would give away the £300 daily allowance members can claim if they attend a sitting.

She told the BBC’s Woman's Hour last year: “I've decided I'm not going to take expenses in the House of Lords. I'm looking into if I can donate it to a few charities.”

She added: “I'm not putting down peers who need to take it. It's expensive going to the House of Lords. It's expensive making travel arrangement etc and they work really hard.

“Fortunately, I'm in a position where I don't need to take my expenses, so I would like to give them to a group of charities, maybe one a month or something.”

Baroness Mone entered the House of Lords in mid-October last year.

Official documents show that that month she claimed the £300 attendance allowance for six days, totalling £1,800.

In November, the latest month for which figures are available, she received the allowance for seven days, a total of £2,100.

A spokesman for Baroness Mone said that she had "given away every penny", adding that the recipients would be announced annually.

Under new rules introduced in 2010 peers are entitled to claim a £300 daily allowance, which is designed to cover all expenses except travel.

They can also elect to claim a reduced allowance of £150 a day, or not claim at all.

Last year, senior Scottish business figures questioned Baroness Mone's business acumen after Mr Cameron asked her to lead a review into how to encourage start-up businesses in disadvantaged areas.

Her appointment coincided with the news she was also being made a Conservative peer.

She faced further questions when pictures emerged of her using a chauffeur-driven government car to carry out the study, attacks she rejected as "unfair", saying that she was trying to "help other people achieve their dreams".

There was more criticism after it emerged that one of her first acts as a peer was to vote for the then proposed cuts to tax credits.

In an interview before her first speech in the Lords earlier this year she hit out at her critics, saying that she had been targeted because she was Scottish and glamorous.

Earlier this year, Baroness Mone altered the status of her company MGM Media, ending the requirement for it to file public accounts.

Her former business, Ultimo, was sold to a Sri Lanka-based group in 2014.
