In the 1966 General Election Megan Lloyd George was elected the Labour MP for Carmarthen, beating, among others, the president of Plaid Cymru, Gwynfor Evans. Megan Lloyd George had held the seat for Labour since 1957, but two months after the election she died and a by-election was called.

Gwynfor Evans once again stood for the seat as the Plaid Cymru candidate even though, three months earlier, he was beaten by both the Labour and the Liberal candidate, only receiving 16.1% of the vote. This time he won the seat gaining 39.0% of the vote, and a majority of 2,436 over the Labour candidate Gwilym Prys Davies.
Gwynfor Evans was the first Plaid Cymru Member of Parliament, and he represented Carmarthen until he lost his seat in 1970. He returned to represent Carmarthen as a Plaid Cymru MP for a period of five years between 1974 and 1979. Gwynfor Evans's success in Carmarthen gave Plaid Cymru the boost the party needed which led to a period of increased support in Wales.

"Plaid Cymru became credible, an appealing alternative to an apparently ageing, timorous, and entrenched Labour Party, which showed all the symptoms of too long a monopoly of power."
