A united opposition on Wednesday questioned Prime Minister Narendra Modi's continued silence and absence inside the house despite growing demands for him to speak on the demonetisation issue.

Alleging that it sends a wrong message if prime minister keeps shying away from a debate, BSP chief Mayawati on Wednesday that a debate is a must because otherwise the BJP government looks like it has done something wrong. "Puri daal kali lag rahi hai."

"Main poochna chahti hoon prime minister se ki agar unhone itna acha kaam kiya hai to vo ghabra kyu rahe hain? (I want to ask PM Modi that if he has taken a decision which is so good why is he scared?) I urge President to summon Modi and ask him to take measures to solve the problems faced by people post demonetisation move," Mayawati told the media.

While, Speaking to the media outside Parliament, Rahul Gandhi alleged that the government and the prime minister are not allowing a debate in the House. "We have filed an adjournment motion in the House and we want Modi to discuss the issue with us," says Rahul Gandhi

There are thirteen opposition parties, baring the Left and the Aam Aadmi Party, protested at Parliament's Gandhi Statue demanding answers on demonetisation.

Among the protestors were leaders from the Congress, the Trinamool Congress and the BSP.

Although the Left did not join the protest, it said that it would mount a separate protest later in the day.

CPI leader D. Raja told the media that "approaching the President is the final option" if Modi did not respond to questions from the opposition.

"Seventy people have lost their lives. Is this a small matter," Jyotiraditya Scindia of the Congress said.
