Yadav said the absence of anybody from JD-U or Left parties at the time when Mukherjee filed his nomination made it clear that there was "no divide in NDA or Left" while parties may have decided differently on the issue of Presidential election.
"Our support for UPA's Presidential nominee is not support to UPA or its policies. We are against UPA's policies, which have pushed the country to the brink of ruin. There is no divide in the Opposition on this main issue," Yadav, who is also NDA Convernor, said.
"This is totally wrong" Yadav said when asked whether his party was gravitating towards Congress and UPA.
He said his party was in favour of a consensus on the issue of Presidential election and backed Mukherjee as he is set to win.
The JD-U chief also pointed to two previous 'Bharat Bandhs' on the issue of petrol price hikes this year and in 2010 in which parties from the Left and the Right had organised protests on the same day.
Yadav was a key force behind the Opposition unity during those bandhs.

UPA was keen that representatives from JD-U and CPI-M also attend the nomination filing by 77-year-old Mukherjee. A number of ministers had also urged Yadav in particular to be present during the event. CPI-M General Secretary Prakash Karat was also requested to attend it.
While JD-U and Shiv Sena from the NDA camp have supported Mukherjee with BJP and Akali Dal choosing to back P A Sangma, division over the issue were also apparent in the Left. CPI-M and Forward Bloc have decided to back Mukherjee's candidature while CPI and RSP have decided to abstain.
