"The continuation of UDF rule is necessary for the better future of Kerala. I don't think controversies will affect its electoral prospects," Antony told reporters here.
Speaking on solar scam which is rocking the government, Antony said the Justice G Sivarajan Panel, probing the scandal was appointed on the basis of demands raised by opposition parties.
"So they (the opposition) should show patience. They should wait for the Commission report," Antony said, adding, action should be taken against those found guilty in the scam.
"No decision can be taken on the basis of an accused's statement," he said.
His statement comes days after CPI-M leader Pinarayi Vijayan questioned the "silence" of Congress leaders such as Antony over solar scam and bar bribery charges haunting the Chandy regime.
Vijayan had said "silence" of Antony, known as "Mr Clean" was a pointer to the "moral bankruptcy" of Congress.
