An adventurer bidding to become the youngest woman to ski solo to the South Pole hopes to raise funds for her trip by pledging to get a tattoo on her bottom.

Mollie Hughes, 29, said she will undergo the inking in return for a £15,000 donation.

Ms Hughes is already a record breaker, having become the youngest female to successfully climb both the north and south sides of Everest, the world's highest mountain, at the age of 26.

The Edinburgh-based explorer is preparing for a solo trek across Antarctica, hauling a 90kg sled on the 702-mile journey to the South Pole in temperatures of around -50C.

Only six women and 17 men have successfully completed the trip she is planning without making any stops to resupply.

She has already raised £60,000 in funding for the challenge but still needs to find another £15,000 before October.

To help achieve that she has pledged to get a tattoo on the cheek of her bottom if someone donates that amount.

The winning bidder will be free to select the tattoo design of their choice.

She already has a tattoo of two kissing chickens on her right bottom cheek after conducting a similar auction to raise funds for an Everest climb.

Devon-born Ms Hughes said: "I auctioned my bum back in 2011 for my Everest expedition and, while my dad wasn't best pleased, it helped me raise the money I needed.

"I'm now eight years older and eight years wiser, therefore my left bum cheek is going to be auctioned off for no less than £15,000.

"The winning bidder can have any tattoo they want on it, anything at all. This is how much I want to go to Antarctica."

She said she hoped her expedition would "help inspire women of all ages to push their comfort zones and realise what they are capable of".

Ms Hughes added: "I'm going to try to ski alone and unsupported across 702 miles of the world's largest desert.

"It's an immense physical and mental challenge but gaining sponsorship to help fund my expeditions is always the biggest hurdle I face.

"I've raised a significant amount already but I still need to raise the final £15,000 before October in order to take on this expedition and attempt to make history."

The explorer will set off from the UK in mid-November and hopes to return in early January - with plans for a speaking tour about her adventure after that.
