BJP MP Maheish Girri on hunger strike over allegations against him

Kejriwal has alleged Girri linked to man who murdered civic body official

BJP Rajya Sabha member Subramanian Swamy today joined party colleague Maheish Girri in a hunger strike outside Arvind Kejriwal's home in Delhi, saying that "after Raghuram Rajan", he will now focus on exposing the Chief Minister."All his life he (Kejriwal) has done fraud. He says he was a meritorious student in IIT but I have records of how he got his admission...which I will reveal in a press conference. Till now I was Rajan ke peechhe (was going after Raghuram Rajan) and he is now gone," Mr Swamy said.Maheish Girri, a BJP MP from Delhi, has been on a protest since yesterday. He wants the Chief Minister to apologise for accusing him of a role in the recent murder of MM Khan, an official of the civic body New Delhi Municipal Council (NDMC)."Question me if needed, arrest me if required," said Mr Girri, who has challenged Mr Kejriwal to an open debate.Mr Kejriwal had earlier in a letter accused Lieutenant Governor Najeeb Jung of trying to protect Mr Girri, who, he said, has links with the man arrested for the murder.Mr Swamy said he and Mr Girri would not end their strike unless Mr Kejriwal apologises or resigns.Mr Kejriwal has shown no signs of relenting as he tweeted this morning on Mr Girri: "He shud be arrested n interrogated by Modi police in MM Khan murder case. Modi police shielding him."MM Khan, an estate officer, was shot dead on May 16, a day before he was to give an order on the terms of the lease of The Connaught, a four-star hotel. The hotel's owner, Ramesh Kakkar, was arrested along with six others for the murder.Mr Kejriwal and his Aam Aadmi Party have alleged that Mr Girri and NDMC Vice Chairman Karan Singh Tanwar, who also belongs to the BJP, played a suspicious role in the murder.The Delhi Police has reportedly said they have not come across any evidence against the two.
