A protégé of Ratu Inoke Takiveikata, the Qaranivalu (Paramount Chief) of Naitasiri Province, Singh was one of only two Indo-Fijians elected on the ticket of the ruling Soqosoqo Duavata ni Lewenivanua (SDL) Party of Prime Minister Laisenia Qarase, when he won the Cunningham Open Constituency at the Parliamentary election held on 6–13 March 2006.
In the previous election, held in 2001, he had attempted to win the Ra Open Constituency for the predominantly Indian National Federation Party.
Fiji Television reported on 28 September that Kepa had written to the Prime Minister a week earlier, charging that Singh was failing to cooperate with her.
Takiveikata, imprisoned for his role in a mutiny linked to the 2000 coup, had attempted to persuade Qarase to retain Singh, according to a Fiji Television report on 8 October, but to no avail.
Fiji Live quoted him on 17 December as saying that he supported the stated intention of the Military to purge corruption and irregularities from the government and bureaucracy.
