Jack McMillan has helped Great Britain qualify in first place for the men’s 4x200m freestyle relay final at the Paris Olympics.

McMillan, from Northern Ireland, set off second after James Guy had established an early lead in the second heat.

The 24-year-old produced a strong leg with a time of 1:45.68 to maintain GB’s advantage, before Kieran Bird and Tom Dean completed the heat in a time of 7:05.11.

McMillan and Bird are set to drop out of the team for the final, with Matt Richards and Duncan Scott poised to return to GB’s line-up for the final.

However, they would still be classed as medallists if GB go on to finish in the top three at 21:15 BST.

Also in the pool on Tuesday night, Daniel Wiffen will look to become the first Olympic gold medallist from Northern Ireland in 36 years when he competes for Ireland in the men’s 800m freestyle final at 20:05 BST.
