Singh was educated in Fiji and at Wellington Polytechnic in New Zealand.[1] He served three terms on the Nadi town council, and was deputy mayor from 1999 to 2001.[2] He is a founding member of the Fiji Cane Growers Association.[2]
Singh contested the 2001 election for the NFP, winning the NadiOpen constituency and becoming the only member of his party to win a seat in the House of Representatives of Fiji. He was subsequently appointed Leader of the Opposition,[3] after Fiji Labour Party leader Mahendra Chaudhry declined the office. In February 2002 he lost his seat after an election petition.[4] Singh appealed this decision to the Supreme Court which ruled that even though the ruling was incorrect, the Constitution did not allow for the appeal of a Court of Disputed Returns ruling.[5] He was replaced as Leader of the Opposition by Mick Beddoes.[6]
Singh was re-elected to Parliament in the 2014 election, winning 1125 votes.[7][3]
In September 2016 the High Court found that Singh had violated the Political Parties (Registration, Conduct, Funding and Disclosures) Decree 2013 by under declaring value of estate held in Nadi.[8] The finding was later upheld by the Court of Appeal, and referred to the Fiji Independent Commission Against Corruption.[9]
Singh gained only 926 votes in the 2018 election and was not re-elected. He contested the 2022 election, winning 642 votes,[10] but again missed out on re-election.
