Scandal-hit charity Kids Company is alleged to have paid a Harley Street doctor thousands of pounds to treat a relative of Camila Batmanghelidjh’s chauffeur.

The Mail on Sunday has been told that the individual, a close relative of driver Jeton ‘Tony’ Cavolli, was among a small group who accepted a total of £750,000 of private healthcare courtesy of Kids Company last year.

The charity logged the expenditure in its internal accounts as ‘clinical staffing costs’ even though Mr Cavolli’s relative was not an employee.

It is understood the relative, whose identity The Mail on Sunday has decided not to reveal, was a patient of the private doctor for a period of several months. When colleagues found out, Ms Batmanghelidjh tried to justify the expenditure by saying Mr Cavolli’s relative had ‘complicated’ health problems.

On Thursday, Ms Batmanghelidjh and Alan Yentob, the chairman of the charity’s trustees, were questioned for three hours by a committee of MPs trying to establish how Kids Company went bust in August with the loss of 600 jobs.

The organisation, which claimed to help underprivileged children, received at least £43 million of Government funding between 2005 and 2015 but closed amid financial chaos and allegations of sexual abuse.

Last week, The Mail on Sunday reported that Kids Company was facing new questions after giving hundreds of thousands of pounds tax-free to employees. And in August, we revealed that Mr Cavolli’s son and daughter were both registered as ‘clients’ of the charity.

According to its rules, this meant the pair would have referred themselves for help because of severe problems in their private lives. Through their ‘client’ status, both children received financial assistance with private school fees.

Cavolli’s daughter attended Dauntsey’s School in Wiltshire on a full academic bursary and left last year having completed her A-Levels.

Kids Company is also understood to have spent about £50,000 enabling Mr Cavolli’s son to attend Fairley House School for dyslexic children in London.

The charity said it did not directly pay his fees, but for the services of a speech and language therapist.

When The Mail on Sunday approached Mr Cavolli on Friday, he denied being Ms Batmanghelidjh’s driver, insisting he was the charity’s ‘operations manager’. But former members of staff said he had been her driver for ‘years’.

Last night a source said: ‘We couldn’t believe Camila was allowing funds donated to a children’s charity to be spent on an adult’s private healthcare. Camila didn’t see the problem with it.’

Mr Cavolli, 46, is originally from Albania and has worked for Ms Batmanghelidjh for about 20 years.

He is understood to have been paid at least £40,000 per year. Ms Batmanghelidjh’s 2006 book Shattered Lives included a warm tribute to his ‘tenacity and wisdom’.

Kids Company is being investigated by the Charity Commission, the National Audit Office and the police.

A source said the Charity Commission was aware of claims concerning Mr Cavolli and his family.
