PORT-OF-SPAIN, Trinidad (AP) —Trinidad and Tobago's former prime minister has resigned as his party's leader following its defeat in parliamentary elections.

Patrick Manning says he accepts responsibility for the vote that ousted the People's National Movement after nine years in power.
A five-party coalition gained a 29-12 advantage in the Caribbean nation's parliament in the May 31 election. Coalition leader Kamla Persad-Bissessar has become the country's first female prime minister.

Many party faithful are angry with Manning for calling elections halfway through his five-year term in a gamble that he never fully explained.

Some booed as Manning left party headquarters under a police escort after announcing his resignation Thursday evening.
