Rajya Sabha Chairman M Venkaiah Naidu voiced strong concern on Friday over the conduct of some MPs in the Upper House of Parliament during their protest over the Pegasus snooping row and other issues, saying such conduct lowered the dignity and prestige of the House.

Appealing to the members to maintain decorum and decency in the House, he said some MPs were whistling while some others used placards to block the view of ministers.

A few others placed their hands over the shoulders of the marshals when the MPs of opposition parties such as the Congress and the TMC were protesting over different issues in the Well of the House.

"All these things are taking the House to a new low. I am very much concerned about this," Naidu said at the start of the day's business. "I only request to all the members to see that the decency and dignity of the House is maintained. That is my earnest appeal. There is a limit to patience and we should not exhaust the patience of the House."

He said the two options before him are to either allow such conduct and convert the House into a "bazaar" or take action.

"House has a decorum, prestige and practice. That has to be seen," he said.

While protesting over issues is fine, the dignity and the prestige of the House should not be compromised, Naidu said.

MPs from opposition parties have stalled the proceedings in the Rajya Sabha since the start of the Monsoon Session of Parliament on July 19 over issues ranging from the use of Israeli-made, military-grade Pegasus spyware to snoop on political rivals, critics of the government and journalists, to contentious farm laws and the fuel price hike.

"It was brought to my notice that some members are whistling in the House. 'Siti baja rahe hai apni purani aadat se' (whistling because of an old habit). This is House," Naidu said. "Secondly, some members are putting their hands on the shoulders of the marshals. I do not know what prompted them."

Also, some members carrying placards are standing in front of the ministers, blocking their view, he said.

"There are two ways (to deal with this) -- one, ignore this and allow this to become a bazaar (market). 'Har ek apna siti bajata rahe, bajate raho' (everyone can whistle)," Naidu said. "Second, taking action."
