Soon after the 2006 election, Singh was appointed Minister of State for Youth and Sports. In this role he was subordinate to Ro Teimumu Kepa, with whom his working relationship was tense. 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. When he started publicly querying what he said were discrepancies in the accounts of the Sports Ministry and especially the Fiji Sports Council. He was dismissed on 13 October 2006. 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.
Following the military coup which deposed the Qarase government on 5 December 2006, Singh declared his willingness to cooperate with the new regime. 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.
On 26 May 2007 Singh told Fiji television that he had resigned from the SDL and wished to contest the next election, but not for his former party.[1]
