Welsh Assembly Assumes Its Celtic Name - Senedd Cymru

The National Assembly for Wales will now be known as the Senedd Cymru. The name change enjoys approximately 75% popular support.

The legislation to change the name of the Assembly for Wales to the Senedd Cymru was passed by the Welsh Parliament  in November 2019 and received  Royal Assent in January

The 60 members of the Senedd Cymru will now be known as Members of the Senedd (MS) or Aelod o’r Senedd (AS) in Welsh.

The new name is written in law in the Senedd and Elections (Wales) Act and the date was picked because it is exactly one year from the scheduled date of the 2021 Senedd Elections.

Wales-On-Line quotes Elin Jones, the Presiding Officer of the Senedd since 2016. Jones commented on the name change: 

“Now, more than ever, our citizens expect a strong national parliament working for Wales: Members asking questions of the Government, scrutinising emergency powers and laws, and representing their communities to the best of their ability in the Senedd. The role of our parliament is of far more significance than its name. But it is right that the name reflects the range of powers and responsibilities this parliament holds on behalf of the people of Wales. The Senedd today is a very different institution to the one established as the Assembly in 1999. Now with full law-making powers and the ability to vary taxes, the new name reflects the Senedd's constitutional status as a national parliament.”
