Political career
1991
Imbert first entered elected politics on 16 December 1991 by winning the Diego Martin East seat for the PNM in the 1991 general elections, defeating the incumbent Anthony Smart of the NAR with 7,111 votes. He was appointed the Minister of Works and Transport and Minister of Local Government in the PNM Administration during the four years following the election.
1995–2001
In the 1995 general election, which was called by the then Prime Minister Patrick Manning one year ahead of schedule, he once again won the seat of Diego Martin East for the PNM, although PNM did not win the election. He also contested general elections in 2000 and 2001, winning his seat on both occasions. In 2001, after the general election of December 2001, the PNM was appointed by the then President of Trinidad and Tobago, A.N.R. Robinson, as the government, although it had tied, 18 seats to 18 seats, with the United National Congress in the election. In this short-lived government, which lasted for 9-month until the financial year expired in September 2002, Imbert served as Minister of Health
2002
Imbert won his seat once more in 2002 and was re-elected the Member of Parliament for the constituency of Diego Martin East. He was re-appointed Minister of Health and served in that position until 2003, when he was appointed Minister of Science, Technology and Tertiary Education. In 2005, after the resignation of the then Minister of Works and Transport, Franklin Khan, Imbert was appointed Minister of Works and Transport.
2007
In 2007, his constituency, Diego Martin East, was renamed Diego Martin North/East due to boundary changes, and in the general election of 2007, Imbert won his seat again, for the sixth time. He was re-appointed Minister of Works and Transport and served in this position until the general election of May 2010, when the PNM lost the government. Imbert was also appointed as the Leader of Government Business in the House of Representatives of Trinidad and Tobago from November 2007 to May 2010
2010
In the 2010 general election, after the then Prime Minister Patrick Manning called a snap election, Imbert won his seat, Diego Martin North/East, for the seventh time. However, the PNM lost the overall election, winning only 12 out of 41 seats in the House of Representatives, and he became a member of the Parliamentary Opposition for the second time in his political career.
2015
In the 2015 general election held on 7 September, Imbert once again won the seat of Diego Martin North/East with the largest ever vote count in his political career. With a tally of over 12,000 votes, Imbert defeated his rival by a margin greater than 7000 votes. The People's National Movement won the general election with 23 out of the possible 41 seats and following this victory, Imbert was appointed Minister of Finance by Prime Minister Dr Keith Rowley.
