Some 10,000 people have taken to the streets of the Nepalese capital, Kathmandu, to support opposition rallies against King Gyanendra.
The protests have resumed in earnest after the monsoon season
The four main opposition parties have been holding rallies since King Gyanendra sacked the prime minister in 2002 and assumed executive powers.
The king reinstated the Prime Minister, Sher Bahadur Deuba, earlier this year.
But opposition parties say they are not convinced he has been given back all the powers taken from him.
During the rally on Tuesday, protesters chanted slogans against the king and demanded the restoration of parliament.
Some also demanded elections for the constituent assembly, a move which Nepal's Maoist rebels believe will pave the way for their republican agenda.
The opposition had been forced to suspend its rallies because of heavy rains during the recent monsoon season.
But now with the skies beginning to clear, they have taken to the streets once again to demand the reinstatement of the parliament or the formation of an all-party government.
Earlier on Tuesday, several hundred people took part in a rally in Kathmandu, to press for an end to the country's long-running civil war.
Buddhist monks and Hindu priests joined schoolchildren, rights activists, lawyers and ordinary Nepalis in lighting candles and singing hymns.
The event was held to mark International Day for Peace.
Some 9,000 people have died in Nepal since Maoists began an armed struggle for a communist republic in 1996.
