Under mounting pressure to quit over alleged land scams, Karnataka Chief Minister B S Yeddyurappa is making a last ditch attempt to convince the BJP high command that he should be allowed to continue in the top post.Amid reports that the top BJP leadership is weighing the pros and cons of axing him to save the party's image, Yeddyurappa will leave for New Delhi on Sunday evening on his second visit to the capital in the last three days to present his case.The beleaguered Yeddyurappa, under intense attack from the opposition, particularly JDS, would tell the central leadership that he commanded majority and that he cannot be sacked unilaterally.Sources close to him told PTI that more than a dozen ministers and some MLAs might accompany the Chief Minister to Delhi and some more may join them later.Meanwhile, the Core Committee of BJP is meeting in Delhi on Sunday, a day after JDS levelled a fresh charge against Yeddyurappa's kin that they had sold land worth 20 crore rupees to a mining firm and raised doubts about its ownership.Yeddyurappa has rejected the charges and claimed the opposition wanted to topple his government.
