Opposition INDIA alliance leaders staged a protest near the Gandhi statue in the Parliament complex on Friday, a day after 14 MPs were suspended.

While Derek O'Brien of the Trinamool Congress (TMC) was suspended from the Rajya Sabha on Thursday, 13 opposition MPs, including nine from the Congress and the DMK's Kanimozhi, were suspended from the Lok Sabha.

O'Brien joined the opposition MPs wearing a T-shirt saying he was on a 'silent protest'.

Former Congress president Sonia Gandhi also joined the protesters in their demonstration.

The suspended MPs held placards saying they were suspended for speaking up, while the "culprit BJP MP" roamed free. The Congress has been demanding strict action against BJP MP Pratap Simha who provided the visitor passes to the intruders.

"Suspension and expulsion is nothing new for this government, last week Mahua Moitra got expelled. This week, the BJP MP from Mysore who issued the passes for the intruders is moving freely, and I and my colleagues have been suspended for raising the voice of the people of India, a very genuine demand that the home minister and the prime minister should speak in Parliament," said Hibi Eden, one of the MPs who was suspended from the Lok Sabha.

Both the Lok Sabha and Rajya Sabha were adjourned for the day amid opposition protests.
