He IS The Twisted Firestarter !

BBC News :

Labour peer and MSP Mike Watson has pleaded guilty to deliberately starting a fire at an Edinburgh hotel last year.
Watson, 56, who represents Glasgow Cathcart, set fire to curtains at the Prestonfield Hotel in November 2004 after a political function.

At Edinburgh Sheriff Court on Thursday, a not guilty plea to a second fire-raising charge was accepted.

Sentence has been deferred for three weeks. Watson said he intended to resign from the Scottish Parliament.
