GB claim relay gold with photo-finish touch

Great Britain's women's 4x100m relay team celebrated a gold medal victory after a race that came down to the final stroke.

The contest between Great Britain and Italy remained tightly contested through the closing stretch, with the outcome uncertain until the very last touch of the wall. In the end, the British swimmers narrowly out-touched their Italian rivals to secure the win.

Italy finished in second place after a closely fought battle that was described as one of the most dramatic finishes of the competition.
