Carol. I think DH has answered your question.

He was convicted for inciting racial hatred and according to the BBC site he got:

"Three months custody for his part in the production and distribution of a racist and anti-Semitic leaflet during the 1999 European election campaign."

I presume the BBC is accurate in saying the "operation" was one of production and distribution but none of the above means he has to have taken part in any of the distribution.
