Speaking before setting off for Indonesia, the prime minister said: "Putin's war has caused devastation around the world - destroying lives and plunging the international economy into turmoil.We will call out Putin's regime, and lay bare their utter contempt for the kind of international cooperation and respect for sovereignty forums like the G20 represent."There won't even be one of the basic diplomatic niceties of these gatherings this time, what is known as the family photo, where the leaders pose for a group picture.Almost three weeks into the job, this is Mr Sunak's second overseas trip as prime minister, after last week's dash to the COP27 climate summit in Egypt.Meanwhile, back home, as Laura Kuenssberg writes, the Chancellor Jeremy Hunt will continue preparing what is called the Autumn Statement, a budget in all but name, to be delivered on Thursday, just hours after the prime minister gets back home."
