Campaigners for a memorial in London to New Zealand war hero Sir Keith Park are to unveil a model of a statue proposed for Trafalgar Square.
Sir Keith played a pivotal role in defending England during the Battle of Britain in World War II.
The campaign, started by a British millionaire and historian, has attracted support from the mayor of London, other politicians and celebrities.
The unveiling of the statue design on Thursday follows an international competition. It was won by sculptor Les Johnson, who is working on an international slavery memorial statue for Hyde Park.
Supporters hope to get planning consent to display Sir Keith's statue in Trafalgar Square next year.
They want a permanent location in Waterloo Place by 2010 in time for the 70th anniversary celebrations of the Battle of Britain.
