New Delhi, Sep 7 (IANS): The BJP on Tuesday urged social activist Anna Hazare to once again "rise" for the nation and speak to the people from the Jantar Mantar here on the "mess" created by the Aam Aadmi Party (AAP) in the political arena.

"I request you to please rise for the nation, come to Delhi and speak clearly to people from the Jantar Mantar on what you feel about the unhealthy politics of AAP and guide the nation like you did to fight corruption under the past regimes," Bharatiya Janata Party (BJP) Delhi unit President Satish Upadhyay said in his letter to Hazare.

He said the people of Delhi expected purity in governance from Delhi Chief Minister Arvind Kejriwal "as promised during your Jan Andolan days but today Delhi feels ashamed".

"Unfortunately, he has worsened the political atmosphere," the BJP leader added.

Upadhyay said lakhs of people in Delhi saw the AAP convenor as a product of Hazare's Jan Andolan and hoped he will work for a better India.

"People thought of Kejriwal as someone who harboured high ideals and bring the much needeed change in the political atmosphere in the country," the BJP leader said.

"But unfortunately, the people of Delhi stand dejected with the Kejriwal government and his party," Upadhaya said, referring to three AAP ministers who were removed or forced out of the government due to various allegations against them.

Sandeep Kumar was removed as the Social Welfare Minister of Delhi over a sex CD last week, while Jitendra Tomar was asked to resign as Law Minister in June 2015 after he was accused of forging his college degree.

Even Asim Ahmed Khan was removed as Minister for Food and Environment in the wake of a bribery charge in October last year.

Upadhyay wrote the letter after Hazare on Tuesday said that his dream about his one-time protege and Delhi Chief Minister Kejriwal bringing about a positive change in the political system lies "shattered".
