BJP has convened a meeting of its core group in New Delhi today to discuss the crisis in Karnataka. The meeting will also discuss the party's strategy on the 2-G Spectrum issue, Adarsh Housing Society and Commonwealth Games scams.Reports say, that facing the heat after Karnataka Chief Minister B S Yeddyurappa came under attack for allegedly favouring his sons in land allotments, the BJP top brass has decided to take a call on the issue.PTI quoting party sources says, Yeddyurappa has offered to surrender all the land alloted to his sons and order a judicial inquiry into the issue. However, a faction within the party want him to step down saying the land scam has taken the sting out of the BJP attack on the UPA government over 2-G Spectrum, Adarsh Society and CWG issues.
