The Tamil Nadu Assembly session, beginning on Wednesday, is set to be a stormy one with the opposition expected to target the AIADMK government in the poll-bound state on several issues, including its handling of the flood situation last month.

The House meets almost a month after the devastating floods that brought Chennai, Kancheepuram, Tiruvallur and Cuddalore districts to a standstill.

Over 450 persons had died in various rain-related incidents during the north-east monsoon that set in October last year.

A united opposition is expected to raise a series of issues including that of release of excess water from a city reservoir, blamed by them as reason for the deluge in Chennai, even as they are likely to target the government's overall handling of the monsoon season.

Other issues like prohibition are also likely to come up.

On its part, the government is likely to list its achievements in the past four years, with the ruling AIADMK dispensation harping on its various social welfare initiatives.

Governor K Rosaiah is likely to spell out government policies on various issues.

The Business Advisory Committee of the House will later determine the duration of the session.

The tenure of the present 14th Assembly expires in May this year. The first meeting of the present Assembly was on May 23, 2011 after results for elections were declared on May 13, 2011.
