108: the answer
Congratulations to Disgusted in Derry and Alan in Belfast who got the two answers I had been expecting - it is the number of local candidates and the age of the oldest voter here. Also congratulations to Susie Flood who came up with an answer which is correct, but which I hadn't a clue about.
I hear on the radio this morning that Queen's University is looking for 110 people to take part in a trial eating dark cocoa rich chocolate for a week to see if it's good for their hearts. Maybe our candidates plus two liggers could participate.
Under our traditional polling day purdah rules, the BBC doesn't touch any discussion of issues or parties whilst the voters are making their choices. So I shall be maintaining radio silence from now until the polls close at 10 p.m.
