New Brexit secretary Dominic Raab has been accused of 'outright abuse of power' by a former aide.

Rebecca Tott, 21, was Raab's diary secretary until she was sacked after being caught using a sugar daddy website and telling a potential partner she knew 'everything' about the then-housing minister.

A disciplinary hearing found her guilty of bringing the government into disrepute on July 9, the same day Raab was appointed Brexit secretary.

Tott said he was 'aggressive' and would sometimes cut people off 'mid-sentence', accusing him of saying: 'Stop. I don't want to hear from you'

Now, speaking to The Sun, Tott has claimed Raab would scare staff by going into sudden furies.

She said he once treated her 'awfully' when another aide made an error in his diary and sent him to the wrong address.

'We tried to explain but he had no time to listen,' she said. 'He said, "I don't care. There is an issue with diary management in this office".

'I was made to feel small and undervalued. He seemed to be avoiding talking to me, which created an awkward dynamic.'

She added: 'I felt bullied. I was distraught. I felt wrecked by the way he made me feel.'

Tott also claimed Raab brought one of her colleagues to tears by shouting at her over the phone.

He later apologised, she said, claiming he was stressed.

The former civil servant, who is now planning a jaunt around the world, claimed Raab would also refuse to sacrifice his one hour and 15 minutes in the gym every day - even for important business.

She said he was 'aggressive' and would sometimes cut people off 'mid-sentence', accusing him of saying: 'Stop. I don't want to hear from you'.

He would also insist on calling for his government car on journeys that take only seven minutes by foot, Tott claimed.

In April, when Tott was exposed for using SeekingArrangement.com, MI5 investigated potential security threats to the country because of her apparent willingness to share details of Raab's whereabouts.

Tott allegedly discussed her work with an undercover reporter posing as a sugar daddy.

She met the reporter twice – for which she was paid £750 each time – including at a five-star hotel less than a mile from the House of Commons, according to the Daily Mirror.

During each meeting she allegedly boasted about knowing Mr Raab's 'every move' and laughed about the idea of having sex with the reporter on his desk.

She reportedly told the journalist: 'I know everything about him. I know his every move. I know where he is today.'

Ms Tott allegedly told the reporter that she wanted to earn £5,000 a month through SeekingArrangement.com, but that he could have 'full undisputed access' to her for £750.

Although the website insists it is not a front for prostitution, men are expected to pay their dates a monthly allowance – a practice known as 'sugaring'.

When the reporter asked what she was prepared to do for £750, she allegedly answered: 'Whatever you would like to be on offer. You may have full undisputed access to me, to do whatever you so choose.'

Before their first meeting, she messaged: 'You've got my undivided attention for a few hours on Saturday – I'll let your imagination run wild as to what you wish to do with that.

'We'll sort out the transactional part at the beginning so we can relax into one another's company from there on out.'

Ms Tott joined the civil service on a 12-month apprenticeship at 16, earning £18,000.

She was held up as a 'success story' after being offered a full-time role, featuring in promotional blogs and videos in which she spoke of her 'passion' for the job and said her career highlights were her first trip to No 10 and meeting David Cameron when he was prime minister.

She said applying for the apprenticeship instead of going to university was 'the best decision' she had ever made.

A source close to Raab told The Sun that Tott was 'smearing' her former boss with 'false and malicious claims'.

Separately, a Housing Ministry spokesman told the paper it does not recognise the claims.

MailOnline has contacted Raab for comment.
