Ladbrokes Players Snooker Championship
It is the first title Allen has won in Europe following World Opens in China in 2012 and 2013.
Mark has previously played one ranking final in Britain, that was at the 2011 UK Championship when he lost to Judd Trump. He climbs to number six in the world, equalling his career best position.
Ricky Walden, had the highest break of the match, a 92 in the 12th frame, but could not prevent Allen from going on to collect the £100,000 prize.
