Swedish double Olympic pole vault champion Armand ‘Mondo’ Duplantis increased his own world record again on Sunday, clearing 6.28 metres to the delight of the home crowd at the Stockholm Diamond League meet.

Duplantis broke the world record for the 12th time as he sailed over the bar at the first attempt to improve on his 6.27m effort at Clermont-Ferrand in February.

“It’s a magical feeling, it’s hard to explain,” said Duplantis, who had not before broken the record in Sweden.
