Llanbradach and Pwllypant Community Council has unanimously backed a motion declaring its support for Welsh independence.
The move follows Caerphilly Town Council’s motion backing Wales leaving the UK, which was passed in July.
The motion was put forward by Plaid Cymru councillor Colin Mann.
Cllr Mann said: “Most people will have noticed that there has been a move in thinking in Wales where the question of independence is now being considered by many more people than has traditionally been the case.
“It is no wonder that the feeling is growing when we view the chaos in Westminster. We all know that the interests of the people of Wales are usually totally ignored by Westminster government.
“Is it possible to make a bigger mess ourselves than is presently being made in London? I would suggest not.”
Community council chairman David Rees said: “This motion recognises that any move towards further self-determination is by no means simple and supports the exploring of the myriad of issues that will arise before Wales reaches independence.
“At the same time, we must start considering these issues whilst keeping our eyes firmly set on the main goal that the people of Wales make all decisions affecting our population and not rely on mis-government from elsewhere.”
South Wales East AM Delyth Jewell, who recently spoke in favour of independence at a rally in Merthyr Tydfil, said: “With the current shambles in Westminster deepening by the day, it’s little wonder that more and more people are deciding that decisions affecting people’s lives in Wales should be made closer to home.
“But independence isn’t an ideological position: rather, want independence so that we can start our own journey and make decisions that will help the people living in our communities to flourish.
“It was a tremendous honour to address the march in Merthyr alongside Eddie Butler and Neville Southall. I think that even more people will turn to this over the coming months as an idea whose time has come.”
