[1] Thasmeen started his career as a civil servant and after venturing into politics he was elected to Peoples Majlis from Baa Atoll and later he served in Maldives President Maumoon Abdul Gayoom's cabinet and was his running mate in the first multiparty election held in the Maldives in 2008.

Besides native language Dhivehi he is fluent English and understands Arabic (having lived in Egypt for his Masters studies.)

In the October 2008 presidential election, he was the running mate[9] of Maumoon Abdul Gayoom, who was Asia's longest-serving President.

Maldives Police Service was introduced as a separate civilian agency during Mr. Thasmeen's tenure as Minister of Home Affairs.

Many modern scientific methods of investigation in Maldives Police Service were introduced under his instruction, including establishing Forensic Labs and deployment of CCTV camera in strategic points in the capital of Male'.

[12] In a leaked cable titled PROSPECTS FOR REFORM DOMINATE DISCUSSIONS IN MALDIVES the followings were noted: "Home Affairs Minister Ahmed Thasmeen Ali join a cabinet that is growing younger and more dynamic as President Gayoom continues to make changes in an effort to prompt progress in the Special Majlis (parliament) that is considering constitutional reforms.

"One of the main reasons for DRP having to face one of its biggest defeats (2008 Presidential Election) and MDP coming to power and causing despair for most citizens was the fact that the whole presidential campaign was run by Gayoom’s eldest son Farish Maumoon as a family matter", said DRP statement.

Speaking to Miadhu daily[23] Thasmeen said there is no reasonable motive for GMR to hold secret talks with him and the leasing of the airport came in a time when Peoples Majlis is tirelessly working on securing state assets.

In his testimonies to ACC, the Honorary Leader of DRP, Gayyoom said that he was informed about the trip of Thasmeen and Shahid from the media and he got a SMS message stating the same.
