Olympic champion Duplantis improved his own record of 6.21m that he set in winning the world title outdoors in Oregon last year. Competing at the All-Star Perche meeting in Clermont-Ferrand, central France organised by 2012 Olympic pole vault champion Renaud Lavillenie, Duplantis cleared the new record at his third attempt to the delight of the 4,000-strong crowd.
