The squad was initially announced earlier this month for the showpiece event from August 4-13 and with the addition of six more the 87-strong squad will be the largest ever to represent British Athletics at a World Championships.
Meghan Beesley, who will compete in the women’s 400 metres hurdles, Chris Bennett (hammer), Rachel Wallader (shot), Nick Percy (discus), Ieuan Thomas (3000m steeplechase) and Alicia Barrett (100m hurdles) have all been added.
Scottish 400m hurdler Eilidh Doyle will captain the British team after winning a ballot of the GB squad. Defending long jump champion Rutherford has been ruled out of the Championships with an ankle injury sustained during a competition in Italy last month.
Four-time Olympic champion Mo Farah is bidding to defend the 5,000m and 10,000m titles, while Laura Muir, who has qualified for the 1500m and 5,000m, and heptathlete Katarina Johnson-Thompson will also be in the hunt for medals.
