Craig Orwin, a BNP member and member of the armed forces, was photographed doing the nazi salute:

Chris Hurst, another BNP member, was also photographed doing the salute. This caused him to be disowned by his own grandfather, who served during the second world war:

(incidentally, Hurst was attending a music event by a singer idolized by Anders Bering Breivik. Her name is Saga, and you can also see her doing the salute at a similar event:

On another occasion (and a little less direct as he did not salute himself) a BNP councillor in Stoke was revealed to have gleefully posed for a photograph some years before with a group of people performing the fascist salute next to a war memorial. While it's true he wasn't doing it himself, he admitted the incident was 'regrettable' and certainly seems to have had no problem with it in the photograph:

(to be fair, one of them is doing it with the wrong arm. So maybe we shouldn't count it?)
Scott McLean, the then leader of the Scottish BNP, was also secretly filmed delivering nazi salutes at a gathering.
In 2009, a 66 year old member of the BNP in Derbyshire pleaded guilty to making the fascist salute at a demonstration:

Photographs of the BNP candidate for Wirral have also emerged of him admittedly in his youth delivering the Nazi salute (behind the charming slogan of 'White Power' and a swastika):
