Currently, David has taken over as Beijing Bureau Chief for The Economist. David was the Washington bureau chief and "Lexington" columnist of The Economist from 2012 to 2018. Before that he was UK political editor and "Bagehot" columnist of The Economist and before that he was EU correspondent and "Charlemagne" columnist of The Economist. No other journalist at the magazine has written all three of those columns. The postings have given David a front-row seat as economic woes and populist political forces have upended the global world order that some had thought was settled. Over the years David has interviewed heads of state, heads of government, cabinet secretaries, and countless elected politicians and newsmakers, and reported from more than 50 countries.
