The Monsoon session of Parliament is likely to commence from July 20 and is expected to go on for three weeks, officials said on Tuesday.

The Cabinet Committee on Parliamentary Affairs (CCPA) is yet to take a final decision.

Usually, Monsoon and Winter sessions have 20 sittings and are spread over four weeks. But there have been precedents of shorter sessions.

The Monsoon session comes after the ruling BJP's victories in West Bengal, Assam and Puducherry.

The rebellion in TMC and Shiv Sena (UBT) will also play out in the forthcoming session.

A decision by Lok Sabha Speaker Om Birla on the demands of 20 TMC and six Shiv Sena (UBT) MPs seeking recognition as separate groups is awaited.

In the Rajya Sabha, after newly elected and re-elected MPs took oath, the political numbers further tilted in favour of the ruling NDA.

The last session ended in disappointment for the government as a Constitution amendment Bill to implement reservation for women in legislatures in 2029 and increase the number of seats of the Lok Sabha was defeated in the Lower House.

The government is now redrafting the Bill to possibly increase Lok Sabha seats of all States uniformly by 50%.

The population-linked increase in seats has been a major concern for southern parties.
