A BNP activist found guilty of harassment after putting up posters of three convicted killers with the description "illegal immigrant murder scum" has lost an appeal against his conviction.

Andrew Kendall, 32, from Fairfax Drive, Westcliff, claimed he was legally entitled to use the posters, which he put up in Southend High Street in February 2007, to promote his party's views on immigration and crime.

But two senior judges at the High Court in London yesterday ruled Kendall was rightly found guilty by Southend magistrates.

Kendall was appealing against his conviction after he was given an 18-month conditional discharge for causing harassment, alarm or distress.

Mr Justice Keith said while it was accurate to say the three men were illegal immigrants, they had been convicted of manslaughter, and not murder.

The judges also said Kendall should have known his actions might distress the public.
