In a letter to Rajnath Singh, she said such 'tainted' leaders should not be allowed to be associated with the party and vehemently opposed the entry of B Sreeramalu and Reddy brothers of Bellary into BJP.
She has also opposed the entry of former Union Minister and Congress leader Venod Sharma into Haryana Janhit Party (HJC), which is in alliance with the BJP.
Her opposition comes after Sreeramalu yesterday announced that his party was merging with the national party two years after he quit the saffron outfit. This came close on the heels of re-entry of former Karnataka Chief Minister B S Yeddyurappa into BJP after the merger of his outfit Karnataka Janata Paksha.
Sushma's open opposition will force the BJP leadership not to take the Reddy brothers back into the party. The Karnataka unit of BJP is keen to see the merger of BSR Congress in BJP, which is considered to have over 3 per cent votes.
The BSR Congress won four seats in the 2013 assembly elections in Karnataka. The Reddy brothers were said to be close to Yeddyurappa.
