"I will be happy if Mamata Banerjee supports Pranab Mukherjee as the next President of India," Bhattacharya told reporters at the state secretariat here.
Banerjee, whose party Trinamool Congress is a key constituent in the UPA, opposed Mukherjee's candidature for the post of President and announced support for A P J Abdul Kalam.
Though Kalam has expressed his unwillingness to join the fray, Banerjee is yet to spell out her next course of action.
Mukherjee, nominated by UPA as its presidential candidate, will contest against former Lok Sabha Speaker P A Sangma whose candidature was first backed by BJD and AIADMK.
