Northern Ireland's Mark Allen makes his first 147 break at UK Championship

Mark Allen said he knew his 147 break was on from an early stage and has described how he held his nerve to make his first tournament maximum at the UK Championship in York.
The Northern Irishman's clearance came in the seventh frame of his second round match against Rod Lawler, putting him 4-3 up. After leaving the arena to compose himself, he then won the next two frames to complete a 6-4 victory.
