Nambukara Helambage Rajitha Harischandra Senaratne (born 29 May 1950) is a Sri Lankan dentist, politician, member of parliament and former cabinet minister.

[10][11][12] Senaratne became involved in leftist politics whilst serving as general-secretary of the Government Dentists’ Association/Government Dental Surgeons Association between 1975 and 1989.

[7] On 17 October 1988 the JVP attacked an election rally for SLPP presidential candidate Ossie Abeygunasekera at Grandpass in Colombo, killing three.

[20] On 31 March 2000 the Court of Appeal upheld a petition against Senaratne, ruling that he was disqualified from sitting or voting in Parliament as he had done business with state institutions.

[22] Using a legal loophole the UNP re-appointed Senaratne to the vacant National List seat cause by his unseating.

[27] He however lost his ministerial position after the UNF was defeated by the newly formed United People's Freedom Alliance (UPFA).

[4] Senaratne's wife Sujatha was appointed director of the National Hospital of Sri Lanka, a move that was seen a political nepotism.

[38] Senaratne left the UPFA in November 2014 to support common opposition candidate Maithripala Sirisena at the 2015 presidential election.

[56] In July 2015 Senaratne and other supporters of President Sirisena formed the United National Front for Good Governance (UNFGG) to contest the parliamentary election.

[69][70][71] He was flown to the private Mount Elizabeth Hospital in Singapore where he underwent a three-hour heart bypass surgery on 19 February 2016.

[79] Rajitha Senaratne was accused of spreading conspiracy theories during the 2019 Sri Lanka Easter Bombings where he claimed the Presidential Candidate Gotabaya Rajapaksa had funded some members of the National Tawheed Jamaath (NTJ) terrorist group.

After the SLPP lawyers association complained to the police both the actors claiming to be White Van Drivers and Rajitha was arrested.

Colombo Crimes Division (CCD) opened investigations and questioned him in the Negambo Prison where he is being detained by a court order due to another separate incident.
