A heated debate on transparency of commissions is expected at the first meeting of the Financial Services Authority's (FSA) high-level broker group.
Although, the group is due to meet before the end of May, a date has yet to be set.
The FSA's official line is that it is looking at all factors involved in regulating insurance broking and will consult on the details of the rules when the Treasury determines the scope of the regulation.
However, FSA chief executive John Tiner spent time in Australia in April and is known to have been enthusiastic about Australia's system of disclosure of commission.
British Insurance Brokers' Association (Biba) chief executive Mike Williams said, in his meetings with the FSA, the authority hinted heavily that it favoured full disclosure.set against any disclosure.
However, small to medium-sized brokers said they would raise the issue at the first meeting.
The Broker Network managing director Grant Ellis said "We fear it will be done on an ad hoc basis and people will find ways around the regulations."
