New Delhi, Apr 28 (PTI): Calling Jharkhand Chief Minister Shibu Soren's action of voting with the government in Lok Sabha an "act of betrayal", BJP on Wednesday withdrew its support to the JMM government in Jharkhand.

The decision was taken in the party’s parliamentary board meeting which had been convened to discuss the future of ties with JMM in Jharkhand.

Senior party leaders had earlier said that BJP had taken very serious note of Soren's action and is not buying the explanation given by Soren's son Hemant that it has happened by mistake even as the Chief Minister wondered "what difference will it (his vote) make".

"The voting in favour of UPA by Soren is an act of betrayal. The manner in which he has voted is a betrayal of coalition dharma. We have taken it very seriously. Senior party leaders will take a call on it," senior BJP leader Prakash Javdekar said.

Another party leader Venkaiah Naidu had echoed similar views saying "it's a clear betrayal".

"You can't be heading a government with the support of BJP, be in opposition and at the same time, support the ruling party at the Centre. It is not acceptable. On what to do the party will meet and discuss. It is a serious issue," he said.

Naidu also refused to buy the explanation given by Hemant Soren on the issue that his father voted for UPA in a mistake.

Senior party leader from Jharkhand Yashwant Sinha said, "He (Soren) is there (on the Chief Minister's chair) in Jharkhand with our support. Therefore, the least that was expected of him that he would not go to this stage. He could have stayed neutral."

Soren had a meeting with BJP president Nitin Gadkari last night where his decision not to vote with the BJP came up for discussion.
