UNP parliamentarian Sri Ranga is not happy with the government's failure to honour a promise.
It was reported earlier the Economic Development Minister Basil Rajapaksa had assured him and public representatives that the UPFA would not contest in the Mullaitivu district at the forthcoming local government polls to make way for his Citizen's Front to contest in the district.
Following the government assurance, Sri Ranga's party (Citizen's Front) decided to contest the local government elections from the District.
The agreement between Sri Ranga and the government was reached on January 25.
However, when the nominations closed two days later, a UPFA nominations list had been handed over to the Mullaitivu Returning Officer by Minister Rishard Bathiudeen.
Sri Ranga had informed President Mahinda Rajapaksa that he was irked by the government move.
When asked for an explanation, Bathiudeen had said that he had no choice, but to hand the already prepared list as he was given only short notice by Basil to withdraw.
During the vote on the 18th Amendment to the Constitution, the UNP MP voted with the government in favour of it.
