At the 1992 general election, local Greens entered an electoral alliance with Plaid Cymru in the constituency of Ceredigion and Pembroke North. The alliance was successful with Cynog Dafis being returned in a surprise result as the MP, defeating the Liberal Democrat incumbent by over 3,000 votes. The agreement broke down by 1995 following disagreement within the Welsh Green Party over endorsing another party's candidate, though Dafis would go on to serve in parliament as a Plaid Cymru member until 2000, and in the National Assembly of Wales from 1999 until 2003. Dafis later stated that he did not consider himself to be the "first Green MP".
