Tracey Emin flies giant sperm flag

Tracey Emin has unveiled a huge flag featuring a cryptic message painted against a backdrop of swimming sperm.

The controversial artist, 43, wrote "One Secret is to Save Everything" on the banner in red capital letters.



The flag, the second in a series of Southbank Centre commissions, will be displayed in London until 31 July.

Hayward Gallery director Ralph Rugoff praised her "precise sense of paradox and ambiguity in subverting what might be a reassuring formula for happiness".

Emin called the artwork "a flag made from wishful thinking". It has been erected on a 100ft-tall flagpole in London's Jubilee Gardens.
