On 6 May 2011, after months of speculation, Abhisit submitted a royal decree to King Bhumibol to dissolve parliament. Election for the House of Representatives was set for 3 July. Election-related violence began immediately after the election date was set. Pracha Prasopdee, ex-MP for Samut Prakan Province who had won all five of the previous elections, was shot in the back on the night of 10 May. Bail was immediately revoked for opposition leaders Jatuporn Prompan and Nisit Sinthuprai for allegedly violating national security and insulting King Bhumibol after they were released from jail. The opposition leaders were originally jailed for months as part of the 2010 Thai military crackdown on protesters and had been released on bail. They lost their parliamentary immunity after parliament was dissolved.
