India's parliament has disqualified senior opposition leader Rahul Gandhi, a day after he was sentenced to two years in prison in a defamation case.

A parliament notice said that Gandhi "stands disqualified from the membership of Lok Sabha", alluding to the lower house of parliament.

He was convicted by the court for 2019 comments about Prime Minister Narendra Modi's surname at an election rally.

Gandhi was a Congress party MP from Wayanad in the state of Kerala.

He remains on bail for 30 days and has said he will appeal the verdict given by a court in Gujarat state.

Gandhi's party had termed the verdict "erroneous and unsustainable" and pledged to fight the disqualification "both legally and politically".

On Friday, the Congress-led opposition leaders in a protest march in the capital Delhi.

Visuals showed heavy security in the Vijay Chowk area outside the parliament as the opposition leaders stepped out carrying a large banner that read "democracy in danger"
