Questions have been raised over what has happened to cash raised from the sale of a Welsh Conservative office.
The money – potentially thought to be £42,000 – from the sale of a property on Anglesey is "unaccounted for", according to a party member speaking to BBC Wales.
The claims have emerged after the party effectively forced out grassroots Tories from the running of a party federation that covers north west Wales, angering members who say they have been given no proper explanation
The Conservative party said all funds from the sale of the Ynys Môn constituency office had been "used in accordance with party rules".
Conservative party member Nic Conner said: "No one believes that foul play has happened. The money has been spent somewhere but it hasn't been documented properly."
There are concerns that some party members may not want to campaign in the region for the Conservatives, who face a Senedd election in less than a years' time, as a result of what has happened.
The move to take over the local party branch follows growing complaints among grassroots members about the operation of the party in Wales, amid rows over selections and who can stand in Senedd elections.
