The art teacher who resigned from Harrow School after topless pictures of her were circulated online is making a comeback - by taking part in a women's boxing match.

Glamorous Joanne Salley, 37, will enter the ring as part of the only women's fixture at this month's Boodles Boxing Ball at the Grosvenor House Hotel, London.

The former model will come head-to-head with Danielle ‘the Grim’ Raper on Saturday in a bid to raise money for neuroblastoma, a rare cancer which mainly affects children.

The former Miss Northern Ireland, who dated former England rugby star Matt Dawson for six years, resigned from the exclusive school in Middlesex following the furore in 2011.

The pictures, which showed Miss Salley posing provocatively in a pair of tight jeans, had been taken by Fiona Corthine, a fellow teacher who was head of photography.

Mrs Corthine apparently left the memory stick in a school photographic studio where it was found by an inquisitive pupil who then wasted no time in showing his friends. 

When the Cambridge graduate discovered the compromising pictures had been circulated throughout the £34,590-a-year boarding school, she took two weeks off work and later resigned. 

The photos - which Miss Salley believed had been deleted - were also sent to boys at Merchant Taylors' School in Northwood, Hertfordshire, where the teacher had previously worked.

One sixth former said at the time: 'She was topless. Everyone already thought Miss Salley was a babe
anyway so naturally the photo went round the school like wildfire.'

Miss Salley later described how she had been left 'mortified and devastated' by the incident. She also admitted that her former modelling career had caused excitement among pupils when she first arrived at Harrow.

'One of the boys kept sending me love letters, which wasn't really appropriate,' she once said. 

Last year, Miss Salley took part in a charity boxing match at a black tie dinner for Harrow and Eton alumni, which was supported by her former school. 

Miss Salley, a trained ballet dancer and keen polo player from from Dungannon, County Tyrone, was crowned Miss Northern Ireland in 1998 and came runner up in the Miss UK pageant. 

Prior to teaching, she co-hosted The Big Breakfast with Johnny Vaughan and starred in an advert for the Peugeot 106. She also worked for Comic Relief does Fame Academy and as a researcher for the BBC’s Hard Sell.

Following her 2008 split with Mr Dawson, she joined a five-month volunteer programme in Cambodia. She has previously raised money charity by running marathons in Rio and New York and climbing Mount Kilimanjaro.

Before obtaining her teaching qualification, Miss Salley studied for a foundation degree in Art and Design at the University of Ulster and then specialised in Jewellery and Silversmithing. 

She had three stints at Harrow School, during which she taught art, rowing, cross-country running, and cookery skills. She was also a boarding house tutor and took Duke of Edinburgh’s Award trips abroad. 

Harrow was founded in 1572 under a Royal Charter sanctioned by Elizabeth I.

It has educated seven Prime Ministers, including Winston Churchill and Robert Peel, two kings and scores of MPs, lords and foreign statesmen.

Other notable alumni are singer James Blunt, Sherlock Holmes actor Benedict Cumberbatch and Blackadder and Four Weddings writer Richard Curtis.
