Posh Cambridge Uni students strip off for a cheeky skinny dip on the hottest day of the year after glamming up for the annual £500-a-ticket May Ball
On the hottest day of the year, many undergraduates decided to bare all while cooling off in the city's iconic River Cam

POSH Cambridge University students stripped off for a cheeky skinny dip today after partying all night at the prestigious Trinity May Ball.
Around 1,800 undergraduates attended the lavish event yesterday - for which tickets cost more than £500 a couple.
But on the hottest day of the year, many decided to bare all while cooling off in the city's iconic River Cam this morning.
Stunned punters then saw the exhibitionists ditch their tuxedos and elegant ballgowns after attending the largest event of the Cambridge student social calendar.
Guests were treated to a five-course meal served in Trinity Great Hall, then students could tuck in to oysters, a hog roast and a chocolate fountain, while drinks were served from a floating punt on the river.
Party-goers treated to entertainment from comedians, as well as a casino and jazz tent before sitting in punts on the historic Backs to watch the fireworks light up the skies around midnight.
Some partied overnight with drunken punt rides on the River Cam and a champagne breakfast in the college gardens last long into the morning.
It website for the post-exam 151st Trinity Mall Ball said: "Following a triumphant 150th anniversary in 2016, the First and Third Trinity May Ball 2017 Committee have been hard at work setting up for what promises to be a night to remember.
"With the best acts, tastiest food and a very special champagne bar this year promises to be one of the best May Balls to date."
The first ball took place in 1866 when the First Trinity team was head of the river and it has evolved over the 20th century.
It has continued every year since, apart from 1910 when King Edward VII died and between 1939 and 1945 during the Second World War.
