The transitional government lasted until elections in 1957 to a reconstituted Legislative Council with 14 elected members. The PPP won all but two seats, although it had split into two factions, one led by Jagan and the other by Forbes Burnham. Another round of constitutional reform in 1961 led to the creation of the Legislature, consisting of an elected 36-member Legislative Assembly (35 members elected in single-member constituencies, who in turn elected a Speaker) and an appointed 13-member Senate. These elections were again won by the PPP, who took 20 of the 35 directly-elected seats. However, the PPP had only received 1.6% more of the vote than the new People's National Congress (PNC), but had won almost double the number of seats. This resulted in mass demonstrations led by the PNC, a general strike and severe inter-racial violence. After a few weeks the British authorities intervened by sending in troops and the Governor declared a state of emergency.
