hello, i m victoria valentine. we start in india where world leaders are expective to arrive in new delhi in the coming hours, ahead of this weekend s 620 summit. this was earlier us presidentjoe biden departing washington for the summit. uk prime minister rishi sunak is also expected to attend. the 620 group consists of 19 of the world s wealthiest economies and the european union. it accounts for 85% of global economic output and two thirds of its population. it s a key forum for international issues but there are deep divisions over some of these, like the war in ukraine. live now to siddarth varadarajan, the founding editor of the independent indian news website the wire. thank you very much forjoining us here on bbc news. what hope is there that india is able to push to the fore the agenda of the global south? i think for india, the 620 has always been about, in a sense, pushing the ideas, views and interests of the global south. we ve been doing this since 2008,
