Earlier, the OAG obtained an EC report on its investigation into allegations that Thai Rak Thai hired minor political parties in many constituencies to contest the April elections to by-pass the 20 per cent rule.

The agency is required to refer the case to the Constitution Court. If found guilty, the party could be dissolved.

However, the OAG has found that the EC report is incomplete without the required recommendation from the political party registrar, EC chief Vasana Puemlarp. The OAG is set to return the EC report to the election agency today.

The commissioners have argued that the law does not require them to make such a recommendation.

"There is sufficient evidence for the OAG to refer the case to the Constitution Court but we need a recommendation from the EC chairman as to whether the accused party is guilty," Atthaphol said.

"He has the responsibility to do so, and he should not just act as a postman by handing us the report," he said.

Vasana declined to comment yesterday, saying it was a holiday and he wanted to relax.

Meanwhile, Caretaker Prime Minister Thaksin Shinawatra yesterday dismissed as groundless press reports that a number of his Cabinet members would resign.

"They are just rumours. And you know what? Rumours are spread by those who want you to believe they are true," Thaksin told reporters.

He was speaking during a round of golf at a course in Bangkok's Bang Na area in the afternoon.

Caretaker Transport Minister Pongsak Ruktapongpisal, who was among those rumoured to be considering leaving the Cabinet, also rejected the speculation yesterday.

"No way," he said when asked if he was going to leave the Cabinet.

Pongsak was among a handful of Cabinet members joining Thaksin at yesterday's round of golf.

Caretaker Deputy Premier Wissanu Krea-ngam was among a few Cabinet members expected to resign later this month. His cousin, former Cabinet secretary-general Borwornsak Uwanno, quit earlier this month to enter the monkhood.
