Elections to Comhairle nan Eilean Siar (Western Isles council) were held on 3 May 2007, the same day as the other Scottish local government elections and the Scottish Parliament general election. The election was the first one using 9 new wards created as a result of the Local Governance (Scotland) Act 2004,[1] each ward elected three or four councillors using the single transferable vote system form of proportional representation. The new wards replaced 31 single-member wards which used the plurality (first past the post) system of election.
The large majority of the seats were held by independent candidates, similar to other predominantly rural Scottish councils. The Scottish National Party and Scottish Labour Party had a small representation each, and the Scottish Liberal Democrats stood four candidates, all of whom were unsuccessful.
