A Brisbane City councillor referred by her own party to Queensland's corruption watchdog says she is disappointed by the Liberal National Party's "vexatious statement", adding it has not told her what she is accused of doing wrong.

The party will not reveal what the allegations are and Cr Richards says she is also in the dark Brisbane's Lord Mayor has warned people not to jump to conclusions

Earlier today LNP president David Hutchinson said "extremely grave" allegations against Pullenvale councillor Kate Richards arose during a review of her candidacy.

The ABC understands the issues relate to Cr Richards allegedly seeking political donations from a property developer.

The party refused to reveal the nature of the allegations but said it was not prepared to "ignore" the issues.

"We set a very high benchmark for our candidates and we thought that these matters are so serious we had to refer them to the CCC," Mr Hutchinson said.

He said Councillor Richards would not be the LNP's candidate in next year's local government elections and the party would review her LNP membership.

In a statement, Councillor Richards said there was a faction within the party that had been trying to "vilify" her since her preselection for the seat in 2015.

"To allege there are extremely grave claims without providing details to me of these claims is utterly inconsistent with advice sent out to all Queensland local government councils," she said.

Councillor Richards said she was "buoyed by support" from many LNP councillors and others in the party.

In a statement, Brisbane Lord Mayor Adrian Schrinner said he had not been given details about the claims but supported the matter being referred to the Crime and Corruption Commission (CCC) so it could "get to the bottom" of it..

"I understand that Councillor Richards has denied any wrongdoing and we should not jump to any conclusions at this time," he said.

"The correct body to make a determination on such allegations is the CCC … We should now let them get on with their job."

Lawyer Terry O'Gorman, who is representing Councillor Richards, said his client had been the subject of a "kangaroo court" process and had suffered "undermining and white-anting" by the faction.

"What any political party does if they're thinking of disendorsing someone is to give them in writing the allegations, ask them in writing to show cause, and then make a proper decision — no such process has been followed here," he said.

Mr O'Gorman said Councillor Richards attended two meetings with the party during the review process and "very minor issues" were raised.

"They don't come anywhere near corruption, they don't come anywhere near maladministration, and she gave responses to those issues that were raised," he said.

Mr O'Gorman said during both meetings Cr Richards was asked to surrender her phone and sign a confidentiality agreement about the nature of what was discussed.

Councillor Richards and her lawyer are seeking the exact details of the allegations from the CCC and the LNP.

Labor's council Opposition Leader Jared Cassidy called for Councillor Richards to stand down.

"Adrian Schrinner needs to show some leadership and he needs to demand that this councillor gets out of this council," he said.

"We owe it to the people of Brisbane to be completely and utterly aboveboard," he said.

Nominations for the Pullenvale Ward open tomorrow.
