Thiruvananthapuram: Former union minister Shashi Tharoor Wednesday requested the authorities to conduct a "thorough investigation" into the death of his wife Sunanda Pushkar and to conclude the inquiry "rapidly and transparently".

Tharoor's statement came as the central government Wednesday sought a detailed report from the All India Institute of Medical Sciences (AIIMS) in Delhi on the allegation by a forensic doctor that he was pressurised to manipulate the report of Pushkar's autopsy.
