Parliament will probably be dissolved by May 10 at the latest, with a general election likely to be scheduled for July 1 or 2, Deputy Prime Minister Suthep Thaugsuban said on Tuesday.
Before then, Parliament would have to pass three organic law amendment bills in time for the Election Commission to organise the elections.
Asked if the military would be needed to help maintain law and order during the lead-up to the election, Mr Suthep said police would be used instead for this purpose from now until the election day.
They will set up checkpoints and also be responsible for maintaining law and order and providing security for all candidates to campaign in every constituency, he said.
He said it was necessary for the Internal Security Act to remain in place in certain districts of Bangkok, as long as political groups continue to rally.
