Congress president Sonia Gandhi on Tuesday met a group of opposition leaders and held consultations with them to evolve a joint strategy in Parliament, sources said.

NCP supremo Sharad Pawar, J&K National Conference patron Farooq Abdullah, Shiv Sena leader Sanjay Raut and DMK leader T R Baalu were among the leaders who met Gandhi at her 10, Janpath residence.

Sources said more such meetings would be held in the next few days, in a bid to bring all opposition forces together.

Opposition parties have been protesting the suspension of 12 Rajya Sabha MPs and are holding protests, seeking the revocation of their suspensions.

Former Congress chief Rahul Gandhi and leader of Opposition in Rajya Sabha Mallikarjun Kharge were also part of Tuesday's meeting.

According to sources, Sonia Gandhi had invited Uddhav Thackeray and DMK chief MK Stalin. Both deputed their leaders --Raut and Baalu-- respectively.

Earlier in the day, opposition MPs in both Lok Sabha and Rajya Sabha held a protest march from the Gandhi statue in the Parliament complex to Vijay Chowk with Rahul Gandhi alleging that the Opposition is not being allowed to raise issues in Parliament, which is now merely a building and a museum.

"Wherever the Opposition is trying to raise issues, they are suppressed. The government does not allow us to raise issues. This is the murder of democracy. We want to raise issues against the government, but we are not allowed to do so," he told reporters.
