The vote of C P Thakur, Union minister and Bharatiya Janata Party candidate for the prestigious Patna Lok Sabha seat, was cancelled on Tuesday on the ground of breach of secrecy, sources said.
Thakur's wife and a few of his supporters were standing by his side when he was pressing the button on the electronic voting machine at a booth on Fraser Road in Patna, they said.
Unless the voter is infirm, only s/he should be present in the enclosure while casting the vote.
Thakur is locked in a direct contest with the Rashtriya Janata Dal's Ramkripal Yadav.
