Kilmarnock and Irvine Valley

Kilmarnock and Irvine Valley is a county constituency of the Scottish Parliament covering part of the council area of East Ayrshire. Under the additional-member electoral system used for elections to the Scottish Parliament, it elects one Member of the Scottish Parliament (MSP) by the first past the post method of election. It is also one of ten constituencies in the South Scotland electoral region, which elects seven additional members, in addition to the ten constituency MSPs, to produce a form of proportional representation for the region as a whole.

The seat was created for the 2011 Scottish Parliament election, following the redrawing and renaming of the old Kilmarnock and Loudoun constituency which had been in the Central Scotland region. It has been held continuously by Willie Coffey of the Scottish National Party, who was previously the member for Kilmarnock and Loudoun.
