SWINDON swimming star Jazz Carlin has retained her British title in the 400m freestyle after a convincing performance in Glasgow.

Carlin led from start to finish as she came home well ahead of Aimee Willmott but just outside the Welsh record.

Her success capped a tremendous week for the Swindon Tigersharks star having already won gold in the 800m free and silver in the 200m free.

Swindon-born Hannah Miley came home fourth in the same race.
