It is unlikely that anyone but Ian Paisley would have noticed but leaving the chamber after the first session of the newly-elected European Parliament in Strasbourg earlier this summer, he asked why no one was sitting in seat 666. There were a number of obvious reasons, not least that there are only 626 members. But the Euro parliament doesn't work quite as logically as that.
Some seats are reserved for visitors and the official list of seat allocation goes up to 679; seat 666 is blank. A German Christian Democrat was seated in seat 665 but the Italian-sounding person in 667 existed on no known list in the Euro parliament; and there are many lists. Maybe Paisley, with this reference to the devil's number, knew something the rest of us didn't.
