Tom Daley has failed to qualify for the 10 metres platform final

The British diver was keen to improve on his bronze medal of four years ago in Rio

Tom Daley’s bid for Olympic gold in Rio is over after he failed to qualify from the semi-finals of the 10 metres platform event.

The 22-year-old from Plymouth looked well placed to improve on his London 2012 bronze after placing first in Friday’s preliminary round.

But he endured a poor first three rounds of the semi-final at Maria Lenk Aquatics Centre and his inability to recover in the remaining three meant he suffered the ignominy of finishing last of the 18 competitors.

With just the top 12 making it through.
