SECURITY officials at the National Assembly have warned staff they expect Welsh language activists will try to paint slogans inside government buildings in Wales.
Cymdeithas yr Iaith Gymraeg, the Welsh Language Society, has had leaked to it an e-mail sent to Assembly managers.
The e-mail says, "We have received information from South Wales Police instructing the Welsh Assembly Government of a substantial threat from Welsh language protesters.
"They have already daubed graffiti at Cathays Park.
"They have issued a statement of intent to enter Welsh Assembly Government buildings and daub paint once inside.
"You need to make staff aware of this and the need for vigilance is paramount. If you suspect anyone is about to behave in this manner, lock the entrance and inform the police on 999."
Cymdeithas yr Iaith has recently stepped up its campaign for a new Welsh Language Act that would extend language rights into the private sector.
The idea of such an extension is not supported by the Assembly Government and there seems little prospect of legislation along the lines suggested.
Cymdeithas spokesman Hedd Gwynfor said, "Not only have they sent this 'warning' out to Assembly employees, but older members of our society tell me that there was more police surveillance during the rally we held in Cardiff last week than has been witnessed since the investiture of Prince Charles in the Sixties.
"Video cameras were widely used, and the police had images of most of the Cymdeithas leaders on file. This shows a total lack of understanding of Cymdeithas yr Iaith's long tradition of non-violent direct action."
