Speaking to reporters here last night, Singh said Banerjee along with Samajwadi Party president Mulayam Singh Yadav had come up with three names for the President's post and as they were not contesting, she should now back Mukherjee.
Banerjee along with Mulayam had suggested the names of former president APJ Abdul Kalam, Prime Minister Manmohan Singh, and former speaker Somnath Chatterjee for the president's post.
Mulayam had later declared his support to Mukherjee. While speaking to reporters at Shivpuri today, Singh advised the BJP to support Mukherjee to pave the way for his unanimous election.
Responding to a query on his recent remarks against Banerjee, Singh said whatever he said was always his personal opinion which he would continue to express even in the future.
About the recent income tax raids on some people allegedly close to the ruling BJP in Madhya Pradesh, he said their links with Chief Minister Shivraj Singh Chouhan and other ministers should also be probed.
