DAP's M. Manogaran is the candidate for the Cameron Highlands by-election, says Prime Minister Tun Dr Mahathir Mohamad. Manogaran was up against MIC's Datuk C.Sivarraajh in the 14th General Election in May last year, where he narrowly lost, garnering 9,710 votes to Sivarraajh's 10,307. 
On June 4, Manogaran filed a petition seeking a declaration that the outcome of GE14 for the Cameron Highlands Parliamentary seat won by Sivarraajh was null and void for flouting the General Elections Act 1954.
The Election Commission on Dec 28 confirmed that Sivarraajh was not qualified to contest in the by-election.
