Daryll Neita completed a sprint double with victory in the 200m on the final day of the UK Athletics Championships.
The 25-year-old, who claimed a surprise win in the 100m over Dina Asher-Smith on Saturday, clocked a time of 22.34 in the 200m ahead of Beth Dobbin and Imani-Lara Lansiquot.
"This means so much to me today. I've put in so much work to be here," Neita said.
"Words can't explain what it means to be double British champion."
Neita, who becomes the the first woman to achieve the sprint double at the British Championships since 2010, said she was feeling "super confident" as she looked ahead to the World Championships, which will take place between 15 and 24 July in Eugene, Oregon.
"This is a major stepping stone for this year. There's so many championships coming up and I'm in great shape and I'm ready to challenge the rest of the world," she added.
Mitchell-Blake claims men's 200m title
Nethaneel Mitchell-Blake ran a season's best and championship record time of 20.05 to claim gold in the men's 200m, bettering the 20.08 championship record set in 2019 by Adam Gemili, who finished fifth in Manchester.
Mitchell-Blake, 28, and second-placed Joe Ferguson, who also ran a season's best, automatically qualify for the Worlds.
"I needed that win," Mitchell-Blake said. "I want to be the best in the nation and now I can go out and compete with the rest of the world.
"It feels good to run fast and I know there is more in the tank"
Burgin dominates 800m
Max Burgin dominated a strong field in the men's 800m, taking gold with a time of 1:44.54.
The 20-year-old led Dan Rowden and Elliot Giles through the first 400 metres and kicked hard into the final straight to widen the gap and guarantee his position at the World Championships.
"The weather conditions didn't help, the wind really threw it into the mix but I just did what I needed to do and came away with gold," Burgin said.
