Dec 15, Colombo: Sri Lanka's political sources say that the defeat of the budget of a ruling party-dominated urban council has caused a new turmoil in the party ranks of the ruling alliance.

The ruling coalition United People's Freedom Alliance (UPFA) run Peliyagoda Urban Council failed to pass the budget of 2013 on Friday.

Six councilors voted against the budget while only three councilors including Chairman Nihal Gamini Ananda and the Vice Chairman voted in favor of it.

In a dramatic move three councilors of the ruling UPFA voted against their own chairman's budget proposal along with three opposition United National Party members.

Peliyagoda Urban Council borders to Colombo Municipal Council and it is an area that is under the power of Minister of Public Relations Mervyn Silva who is well-known for controversy.

The Peliyagoda Urban Council is in the Gampaha district which is under the leadership of Minister of Economic Development Basil Rajapaksa.
