Solicitor on ecstasy before party added bells and whistles (6,2)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

PIMP (solicitor = one who solicits customers for a prostitute) + E (abbreviation for the drug ecstasy) + DUP (Democratic Unionist Party in Northern Ireland). Pimped up, as a verb = added bells and whistles = modified [something] to make it more exciting.
