White horse sculpture unveiled on the Mall

A life-sized sculpture of a white racehorse has been unveiled on the Mall.

The statue, by artist Mark Wallinger, will stand outside the British Council's headquarters for two years before being taken abroad to be displayed.

The marble and resin work is a copy of a larger, 50 metre, design that Wallinger wants to build at Ebbsfleet in Kent dubbed "The Angel of the South".
