Mottley, who first entered local politics in 1991, when she lost the St. Michael North East constituency to Leroy Brathwaite, took the oath of office before Governor General Sandra Mason and in the presence of family, friends and party supporters.
Attorney Dale Marshall also took the oath of office as attorney general.
Mottley, who between 1994 and 2008 held a succession of ministerial portfolios, led the BLP to a whitewash of the Democratic Labour Party (DLP), led by Freundel Stuart, winning all 30 seats in Parliament.
She was the first female to be appointed attorney general and minister of home affairs in 2001 and is also the youngest ever queen’s counsel in Barbados.
Two years later, she served as the island’s second female deputy prime minister and, following the BLP’s defeat in the 2008 election and Owen Arthur’s resignation as party leader, Mottley was chosen as BLP party leader on Jan., 19, 2008. She also served as the first female Opposition leader when she was sworn in on Feb., 7, 2008.
Mottley joins the late Dame Eugenia Charles of Dominica, Janet Jagan of Guyana, Jamaica’s Portia Simpson Miller and Kamla Persad Bissessar of Trinidad and Tobago as women who have led governments in their respective Caribbean countries.
