A teenager trekked 14 miles across the capital in a bid to visit as many public toilets as possible.

Leah Cartwright, from Limes Farm Estate, set out on a walk across London.

Surrounded by supporters, the 13 year-old zig-zagged from public toilet to public toilet, on a route she had planned herself and in an awareness raising t-shirt she had designed.

The unconventional yomp was in aid of Toilet Twinning, a charity which fights to install safe toilets in developing countries.

Miss Cartwright said: "I saw the devastating impact that not having toilets had, children are struggling to live past the age of 5, and at 13 I knew there was something I could do about it.

"I am overwhelmed by the support I have received."

In total the walk raised more than £1,000 for charity.

Leah's father, Ryan, said: "We couldn't be prouder of Leah, lots of people do sponsored events for charity, but to conceive and organise a walk like this when you are only 13 is an amazing thing."

Miss Cartwright also received a Jack Petchy award for her efforts, after she was nominated by her scoutgroup1st Hainault.
