Hannah Russell has claimed silver in the S12 400m freestyle after just being edged out by Russia's Oxana Savchenko.
There was nothing in the race between first and second, as the lead changed a few times but there were never more than a few tenths of a second between them.
The 16-year-old Briton swam a personal best but had too much to do in the final straight to overturn the Russian.
Savchenko's time was 4:37.89, with Russell 0.71s behind on 4:38.60. Third place went to Deborah Font of Spain with 4:39.75.
