RADIO Carmarthenshire, sister station of Radio Pembrokeshire, is failing its licence obligations and its listeners, the Welsh Language Society has claimed.

The comments followed the arrest of 11 members of Cymdeithas yr Iaith, who stormed the Narberth studio during a live broadcast on Saturday.

Station boss Keri Jones branded the protesters 'terrorists' after broadcasts were temporarily suspended and presenter Aimee Bowen suffered an arm injury.

"Despite 50% of the population of Carmarthenshire speaking Welsh, less than 5% of the station's output is in Welsh," said a society spokesman.

The protesters say they have monitored the nightly three-hour Welsh language programme broadcast as part of the licence agreement and found just eight minutes of the show are actually in Welsh.

"We have talked to Radio Carmarthenshire, but their attitude is absolutely terrible," the spokesman said.

The spokesman added that the society had no idea how Ms Bowen was injured, as it always promoted non-violent direct action.

Mr Jones claimed the station was exceeding its Welsh language provision as defined in its licence and regulated by Ofcom.

"Once again, the Welsh language has hit the headlines for the wrong reasons," he said. "We have been inundated with calls from disgusted listeners upset by this. These people are terrorists, trying to force change through illegal activities."

The society spokesman added: "It is disgusting calling us terrorists. It is using the word far too lightly."

A police spokesman confirmed 11 people had been arrested on suspicion of criminal damage and assault, but released pending further investigation.
