G20 leaders pay respects at Gandhi memorial as they wrap up Indian summit and hand over to Brazil

The Group of 20 rich and developing nations welcomed the African Union as a member - part of Indian Prime Minister Narendra Modi's drive to uplift the Global South. And host India was also able to get the disparate group to sign off on a final statement despite pointed disagreements among powerful members, mostly centred on the European conflict.

India also unveiled an ambitious plan with the United States, the European Union and others to build a rail and shipping corridor linking it with the Middle East and Europe in a bid to strengthen economic growth and political cooperation.

With those major agenda items taken care of, the leaders shook hands Sunday and posed for photos with Modi at the Rajghat memorial site in New Delhi. Each received a shawl made of khadi, a handspun fabric that was promoted by Gandhi during India’s independence movement against the British.

Some leaders - including British Prime Minister Rishi Sunak and last year's G20 host President Joko Widodo of Indonesia - walked to the memorial barefoot in a customary show of respect. US President Joe Biden and others wore slippers as they walked over wet ground spotted with puddles from heavy rain.

The leaders stood before wreaths placed around the memorial, which features an eternal flame and was draped with orange and yellow marigold garlands.

The one reserved for Modi identified him as president of “Bharat” - an ancient Sanskrit name championed by his Hindu nationalist supporters that shot to prominence as the summit approached.

Earlier in the day, Sunak and his wife Akshata Murthy separately took time to visit and offer prayers at the Akshardham Temple, one of Delhi's most prominent Hindu houses of worship.
