A group of council members are petitioning the group's president, Kate Davis, to hold a meeting that would qualify them to vote at a party ''divisional council'' that could overturn Mr Seselja's victory last month over the incumbent Senator Gary Humphries.

The women's council members include former senator Margaret Reid who, along with several other party elders, was unable to vote in the preselection on February 23 at Kingston's Eastlake Football club where Mr Seselja defeated Senator Humphries by 114 votes to 84.

But the result has been challenged, and a party extraordinary meeting where the challenge will be debated has been delayed, providing the opportunity for still more party members to join the voting rolls.

The party's largest branch, Central Electorate, has also signalled its intention to hold a meeting to get more of its members qualified, a move that would further swell the ranks of potential preselectors.

Mr Seselja went on radio on Thursday to attack former party president Gary Kent, the key figure behind the move to challenge the ballot result.

Mr Seselja accused Mr Kent of leaving the party in ''pieces'' after his time at the helm of the ACT division.

On ABC radio Mr Seselja described Mr Kent as the leader of the ''disgruntled rump'' who ''have been out there slagging the party publicly''.

''Many members would remember what it was like when Gary Kent was leading the party a few years ago,'' Mr Seselja said.

''A number of us had to pick up the pieces after he last led it.''

Mr Seselja said the divisional council meeting would decide ''whether to uphold the constitution and whether or not to go back to the days of the leadership of people like Gary Kent which existed five years ago''.

Mr Kent defended his record in the party and said ''my objective is to ensure a fair preselection''.

''No matter who is ultimately preselected to represent the Canberra Liberals in the election this year, they will have my 100 per cent support,'' he said.

Senator Humphries also welcomed the decision to delay the meeting.

''The last thing the party needs is a big meeting of party members that gets declared invalid after it is over, so it is a good thing that we will have a chance to deal with the issue that has been raised, but it obviously won't be next week,'' he told ABC radio.

He expected it would be a well-attended meeting. ''Obviously it does appear that across the party members are anxious to get their voting status up,'' he said.
