"People from the state are facing drought, therefore it is not appropriate to celebrate birthday," Uddhav was quoted as saying in his party mouthpiece 'Saamana' today.
The Sena leader recently underwent an angioplasty to remove three blockages in his arteries at the Lilavati hospital while his father Bal Thackeray is also recuperating currently in the same hospital.
"He (Uddhav) is well, but won't be celebrating the birthday because of drought in the state and also because of his health issues," party spokesman Sanjay Raut told PTI today.
"He will not be meeting anybody today," he added.
