Kongahakankanamage Don David Perera (born 19 November 1924) was a Ceylonese planter, businessman and politician.
[2] At the parliamentary elections in March 1960 Perera contested the Bandaragama electorate, where he lost by 3,123 votes to the United National Party rival, D. C. W.
They were initially dismissed by the Election Judge on 5 June 1966, whereupon an appeal was lodged by the claimants to the Supreme Court.
[8] Following the 1967 parliamentary by-election, further petitions were lodged with the courts seeking the by-election results to be declared void on the grounds that Perera should have been disqualified from running on the grounds that the Supreme Court ruling in 1967 disqualified him under the constitution.
Following a hearing in June 1968 the Supreme Court decided the results of the 1967 by-election be declared void[7] and on 5 March 1969 Kotalawala was appointed as the member for Bandaragama.
