Terminology
When initially set up under the Government of Wales Act 1998, the post was known as First Secretary for Wales (in Welsh Prif Ysgrifennydd Cymru), as Wales was given a less powerful assembly and executive than Northern Ireland and Scotland. This was also attributed to the fact that the Welsh term for First Minister, Prif Weinidog, also translates as Prime Minister, so a different title was chosen to avoid confusion with the Prime Minister of the United Kingdom.
A change of title occurred after the Liberal Democrats formed a coalition government with Labour in the Welsh Assembly in October 2000. The Government of Wales Act 2006 allowed for the post to be officially known as the First Minister and also made the First Minister, Keeper of the Welsh Seal.
