Damien put the idea out there and Keith has quickly responded; check out this superb Dáil seat visualiser which has a record of the composition of the Irish government from the 1st Dáil of 1918 to today’s 29th incarnation.
A great little resource for anyone interested or involved in Irish politics; the way it’s laid out lets you flick through each Government so you can see how the parties have grown and shrunk (and sometimes back again) in an instant. For example, with minimum effort I can now confirm that the last single party majority seen in Ireland was in 1977/21st Dáil, held by Fianna Fáil, or you can point out that Labour’s strongest position was in the 1992/27th Dáil in which they bagged 33 seats; 11 more than their previous best of 22 in 1965/18th Dáil (which they coincidently currently stand at).
Well done Keith, and nice idea Damien; possibly something Irish Election could put into their site; actually a blog-friendly version would be terrific if possible, so people could put it in their sidebars etc. (way out of my abilities, though)
