Guwahati, Jan 07 (Agencies): As the UPA Government battles a series of scams, the Bharatiya Janata Party (BJP) national executive beginning here on Saturday is expected to further sharpen its offensive against the ruling alliance at the Centre on the issue of corruption.

This is the first meeting of the national executive of the party after the 2-G spectrum allocation controversy exploded into a major scam that saw an escalating standoff between the Government and the opposition over the issue of JPC probe into it.

BJP sees the situation as an opportunity after two successive stints in the opposition. Buoyed by the recent revelations on the Bofors pay-offs case by the Income Tax Appellate Tribunal, BJP will prepare a strategy for taking on the government on the corruption cases that have come to light in 2010.

BJP also plans to hold more rallies against corruption across the country to keep the issue alive till the Budget Session of Parliament.

This is the first national executive of BJP after senior leader Jaswant Singh was given the responsibility of winning over more allies and improving relations with the four parties already in the NDA-fold.

The party is eyeing allies like AIADMK in Tamil Nadu, AGP in Assam, INLD in Haryana, TDP and TRS in Andhra Pradesh which had been a part of NDA in the past. Incidentally, Jaswant Singh has a good rapport with leaders like Jayalalithaa and N Chandrababu Naidu.

The impressive victory of BJP and JD(U) in Bihar assembly polls has come as a shot in the arm for BJP which plans to strengthen NDA in case a snap Lok Sabha poll is announced.

The national executive meeting is significant as assembly elections in Assam, West Bengal, Tamil Nadu, Kerala and Pudducherry are not far away.
