Thai candidates and their supporters face jail time if caught campaigning on social media websites Twitter or Facebook on the evening before the July 3 election, police spokesman Prawut Thavornsiri said.
Thai law forbids campaigning after 6 p.m. on the night before the vote until midnight the next day, with offenders facing a 10,000 baht ($326) fine and six months in prison. Prime Minister Abhisit Vejjajiva and Yingluck Shinawatra, who heads the main opposition Pheu Thai party, both plan to hold final campaign rallies tomorrow night.
