British movement, Baron Al

In the February/March issue (#33) of the German
Antifaschistisches Infoblatt there is this piece of info
on Al Baron in the context of an explanation (coming from Graeme
Atkinson of Searchlight) about who Larry O’Hara is:

Since 1992 he (O’Hara) is in touch with two other people.
One is MARK TAHA, a former member of the violent British
Movement, and another is a person who uses the assumed name
of ALEXANDER BARON, also an ex-BM member.
