Edinburgh's Dan Wallace helps Team GB to success in the pool

Edinburgh swimmer Dan Wallace (pictured left) played a key role in helping Team GB to its best night in the pool at an Olympics since the LA games in 1984.
He was part of the men's relay squad which won silver in the 4x200m freestyle behind a United States team which featured Michael Phelps.
The British team also featured fellow Scots, Stephen Milne, Duncan Scott and Englishman James Guy.
Scotland's Robbie Renwick was involved in the heat.
Meanwhile, Team GB's Siobhan O'Connor added to the success with a silver in the 200m individual medley.
The British successes took the swimming tally to one gold and three silvers on the fourth night of finals.
Adam Peaty previously won the 100m breaststroke and Jazz Carlin was second in the 400m freestyle.
Britain's swimmers attracted criticism for winning just one silver and two bronze medals four years ago in home waters, but they have already surpassed that total and there could be more to come.
