"The silence maintained by Rangasamy without expressing his government's stand on the issue gives rise to genuine doubts," CPI state secretary N Kalainathan said in a statement.
The party also announced its support to the bandh called on December 1 by traders and business community here in line with the call given by Confederation of All India Traders to protest against the decision to allow FDI in retail.
The CPI would ensure that the bandh called on Dec 1 turns out to be successful. "FDI is most dangerous as it would only strengthen the foreign investors at the cost of Indian traders and business community. The Centre should drop its decision in the larger of country's economy," he said.
