Rival politicians have pledged to heed the King's call for unity, saying His Majesty had imparted an invaluable lesson at yesterday's public audience from the balcony of the Ananta Samakhom.

In his speech, the monarch reminded the nation of the virtues of unity and how it would ensure peace and happiness for all.

Democrat Party leader Abhisit Vejjajiva said his fellow Democrats viewed the royal advice as a guiding light - to lead the country out of political uncertainty.

"The Democrats will try to overcome the political crisis for the sake of unity," he said.

Abhisit said his party had already ended its electoral boycott as a first step to put national politics back on track.

The Democrats would comply with every recommendation made by the judiciary to end the crisis, he added. And his party would adopt the royal advice on creating a "sufficiency economy" as a model to tackle socio-economic problems.

Thai Rak Thai Party secretary-general Suriya Jungrungreangkit said he felt overwhelmed by the people's loyalty to the monarchy.

Suriya said relevant parties should unite but refused to speculate on whether political bickering would resume after celebrations.

Rival sides have declared a truce during the five days of festivities.

Chat Thai Party deputy leader Wirasak Kowsurat voiced optimism that political rivalries would dissipate in the light of the King's urging.

People's Alliance for Democracy spokesman Suriyasai Katasila said the government should rely on the royal advice as a springboard to foster cooperation in society.

Meanwhile, Caretaker Deputy Prime Minister Wissanu Krea-ngam yesterday refused to confirm or deny a rumour that he and two other Cabinet members would resign after this weekend.

He said it was not proper to talk about such a matter at this time.

Asked if Education Minister Chaturon Chaisang, Deputy PM Surakiart Sathirathai and he would resign after the celebrations, Wissanu said: "Would you allow me not to answer your question?

"I do not even know if I will resign, so how can other people know?" he said.

"While the country celebrates His Majesty's reign, nobody should think about this kind of thing."

The rumour followed the resignation of Cabinet secretary Borwornsak Uwanno on Tuesday.

Later, Udom Kraiwatnusorn, secretary to the education minister, denied Chaturon would resign, saying he had heard nothing to support the rumours.

Deputy Agriculture Minister Adisorn Piengket, who is close to Chaturon, said he would be the first person to know if the education minister would resign. "It's just a rumour to discredit the government," he said.
