Thailand's anti-government protesters on Sunday officially announced an ultimatum of a House dissolution within 24 hours.

The announcement was made by anti-government United front for Democracy against Dictatorship (UDD) core leader Veera Musikapong at about 12:00 p.m. local time, at the main rally site in capital Bangkok.

Hence, the UDD protesters want the answer from the government by 12:00 p.m. local time, on Monday.

Veera said the red-shiretd people will step up pressures on the government, while he did not disclose details yet.
