A Primrose Hill woman is doing a balloon race from Trafalgar Square's fourth plinth to raise money for charity on Wednesday.

Liz Mendes is looking for people to buy balloons which she will then release from the monument as part of Anthony Gormley's art project.

All balloons will be printed with the name of their owner and the one that travels the longest distance will win.

First prize is a night's stay in the 4*Cavendish Hotel with cinema tickets, dinner and a trip on a speed boat thrown in.

All money raised will go to leukaemia charity Karen Morris Memorial Trust which supports patients of the disease and their families.

To find out more about Ms Mendes' charity campaign go to her website www.ontheplinth.co.uk and to buy a balloon go to www.justgiving.com/balloon-race.

Her slot on the plinth runs from 8pm to 9pm on Wednesday August 19.
