Stating that he would resign as BJP legislator from the assembly by the month end, former Karnataka chief minister BS Yeddyurappa said on Thursday that he would focus on building his new party.

"By month end I will tender my resignation as BJP legislator in the state assembly and focus on building my new party," he told reporters after worshipping at Yedyur Siddalingeshwarswamy Temple in Kunigal.

Yeddyurappa said BJP ministers and MPs need not attend his rally at Haveri, but interested legislators could attend it.

"Who ever attends Haveri meeting or not, I will go head with launching my party," he said.

Yeddyurappa said he would not attend the assembly session commencing at Belgaum from December 5.
