The Assembly Government has come under more pressure over its reform of the arts today.
Opposition parties have reacted angrily to a decision not to automatically reappoint quango boss Geraint Talfan Davies to his job.
His term as chairman of the Arts Council of Wales ends in March and Assembly Culture Minister Alun Pugh has decided to advertise the position.
Yesterday the council accused the Government of risking creeping politicisation of the arts by changing the funding rules for major arts organisations.
Waless six biggest arts companies, including the Welsh National Opera, will be funded by the Government and not the council from this year.
Culture Minister Alun Pugh is said to be concerned about access to the arts for people from poor and minority backgrounds.
But council members say this single issue is his only priority in selecting a new chairman.
Tory culture spokeswoman Lisa Francis said: We have long warned about politicisation of the arts in Wales and this statement vindicates our concerns.
I fail to see what is going to be achieved by the Governments approach other than what would amount to a Stalinisation of the arts with Alun Pugh as head of a Politburo of Cultural Correctness.
She has written to him demanding to know why Mr Daviess job had not been renewed.
The councils strategy and policy roles are due to be absorbed by the Assembly Government in 2007.
However it will not be completely abolished, like other high-profile quangos, because it gets lottery money, the Government said.
It is understood opposition parties could unite around the issue.
A Plaid Cymru source said party leader Ieuan Wyn Jones would consider asking the Tories and Liberal Democrats to oppose the minority Labour administrations plans.
A party spokesman said: There will be discussions held over the weekend about which steps to take.
Plaid AM Rhodri Glyn Thomas said: I am saddened that the minister feels that Geraint Talfan Davies no longer has a role to play in steering the Arts Council during this difficult period of transition.
Geraint Talfan Davies is a man of great experience with a strong personality and I can only assume that the minister found these qualities too challenging.
