The Senedd (Welsh Parliament; ) has the power to make legislation in Wales. The parliament was created by the Government of Wales Act 1998, which followed a referendum in 1997. It is a democratically elected body with 60 members known as Members of the Senedd (MSs). Of these 40 MSs are elected using First past the post in single member constituencies and a further 20 MSs are elected using the D'Hondt method, a form of party-list proportional representation in five additional member regions with each region electing 4 MSs. The Senedd had no powers to initiate primary legislation until limited law-making powers were gained through the Government of Wales Act 2006. Its primary law-making powers were enhanced following a Yes vote in the referendum on 3 March 2011, making it possible for it to legislate in the 20 areas that are devolved without having to consult the UK Parliament, nor the Secretary of State for Wales. The Senedd may also delegate authority to enact legislation through Welsh Statutory Instruments. Under the Wales Act 2017 the Senedd came into line with Scotland and Northern Ireland and moved to a resevered powers model.
