Conservatives are trying to remove the father of an AM and MP from a list of assembly election candidates - after he called for the body to be scrapped.
Peter Davies believes the Welsh assembly should be abolished
Tory assembly leader Nick Bourne has asked officials to block Peter Davies as a candidate after he publicly advocated abolishing the assembly.
Mr Davies is a Newport councillor and father of Monmouth MP/AM David Davies.
Tory policy is to support the assembly but its manifesto for the 2005 election pledged to offer a chance to scrap it.
Peter Davies said in a letter to the Western Mail: "Since only 24.7% of the Welsh people voted for an assembly and now after eight years we know that it doesn't work, the best way to save money would be to abolish the assembly and all its members!"
Mr Bourne said Mr Davies's letter "hadn't gone unnoticed" and that Welsh party's chairman Lyndon Jones and director, Matthew Lane have been asked to remove him from the list "urgently".
David Davies said his father has a right to his opinion
Mr Davies is on the approved list of candidates but has yet to be selected for a particular seat or region.
He wrote that abolition would save money and "give us better government in Wales including reduced hospital waiting lists, a higher standard of education, and local government without interference from the Welsh Assembly Government.
"The abolition of the national assembly would also have the additional advantage of preventing Britain being broken up into regions by the European Union so that the commissioners in Brussels can run our country in their undemocratic, inefficient, self-serving fashion," he added.
David Davies said his father had a right to his opinion and that plenty of politicians stand for or are elected to serve in institutions with which they disagree.
He said they see their role as holding that institution to account, despite wanting to abolish its legislative power over the region or country they represent.
The Welsh Tories are now "looking at the letter and checking the rules".
They admit that Peter Davies would have the right to a legal challenge if he is removed from the approved list of candidates.
