In September 2006, several of the party's top leaders, including Saber Hossain Chowdhury MP and Asaduzzaman Nur MP, were hospitalised after being critically injured by police beatings while they demonstrated in support of electoral-law reforms. Starting in late October 2006, the Awami League led alliance carried out a series of nationwide demonstrations and blockades centring on the selection of the leader of the interim caretaker administration to oversee the 2007 elections. Although an election was scheduled to take place on 22 January 2007 that the Awami League decided to boycott, the country's military intervened on 11 January 2007 and installed an interim government composed of retired bureaucrats and military officers.
