From the BBC website -

"The UDP has strong links with the banned loyalist paramilitary group, the Ulster Freedom Fighters.
The UDP left the peace talks in January 1998 after the UFF admitted taking part in the killing of three Catholics. If it had not left, it would have been suspended as parties are not allowed in the talks if groups to which they are linked take part in violence.
The party was re-admitted in February 1998 and later signed up to the Good Friday Agreement.
The UDP leader is Gary McMichael. The party has no MPs and to the surprise of many failed to win any assembly seats."

or did you mean the Democratic Unionist Party "Gillian"? - you seem a little confused for a "good Ulster Woman"

I don't think you have much to teach "Gillian"
