Team GB's swimmers have won two silver medals on day four of the Olympics.

Siobhan-Marie O'Connor clinched her silver medal in the 200m individual medley, whilst the men's team came in second in the 4x200m freestyle relay.

It was a pretty successful day for the most successful Olympian of all time, Michael Phelps.

Ricky is in Rio with a round-up of the action on day four.
