Members of Plaid Cymru have backed calls to boycott the television licence fee in an effort to defend the independence of Welsh-language broadcaster S4C.
Delegates at Plaid's Annual Conference voted overwhelmingly to support the controversial boycott, which stems from a proposed Government shake-up of S4C funding.
The Government plans to cut the channel's £100 million direct grant by 25%. Responsibility for funding S4C would also transfer from the Department for Culture, Media and Sport to the BBC, who will have to fund the Welsh broadcaster from TV licence revenue.
Plaid MEP Jill Evans is the latest in a growing list of high profile TV licence "refusniks" opposed to greater BBC involvement in Welsh broadcasting.
A Plaid statement said: "Conference agreed that it would offer support to those who choose in a personal capacity to make the decision to withhold their TV licence fee because of their strength of feeling."
A TV Licensing spokesperson said: "Regardless of personal opinion, if you don't have a valid TV licence when you need one, it's against the law and you risk a prosecution and a fine of up to £1,000."
A BBC spokeswoman said: "The UK Government’s decision to change the funding arrangements for S4C cannot and does not amount to a BBC takeover of S4C. The BBC is fully committed to Welsh language provision and to an editorially independent S4C."
