In the Rio gloom, the pink clays illuminate the dank. Two luminous explosions move Steven Scott nearer to a medal...

Kneale clings on, but Scott can't miss. 24 out of 24 now.

There will be 30 shots in total, 15 pairs of two. Scott, the shorter of the two, is in white, the tall Kneale is in navy blue. Scott is two ahead with five pairs to come...

Scott is still destroying the pink targets. 16 out of 16. Kneale has missed! He's two behind...

Scott, by the way, is coached by Sheikh Ahmed Al Maktoum, who led Peter Wilson to gold in London. He's currently 12-11 up with a perfect record.

No respite, we're straight into this. Great Britain is assured of a bronze medal, but who will win it? Steven Scott and Tim Kneale are back in position...

It is a long walk for James Willett, it is not his day. 

Britain are assured a medal.

Steve Scott destroys both targets! Both Britons are into the bronze-medal match!

Kneale hits... Willett misses!

So, we know at least one Briton will have a chance of a medal. Remember, Joe Clarke goes for canoeing gold at 19:36. He's the shootout...

Steven Scott will be ruing his double miss earlier on in that semi-final.

Are you following this? Fehaid Aldeehani and Italian Marco Innocenti are through to the final. British pair Tim Kneale and Steven Scott, along with Aussie James Willet, finish level on 26 out of 30. That trio go into a shootout for a place in the bronze-medal match.

Kneale finishes with 26, but that's not good enough for the final. 26 is the most Scott can finish with...

Tim Kneale looks out of gold-medal contention. He may have to focus on the bronze. Miss for Steve Scott! Aldeehani takes the first spot in the gold-medal match...

Australian James Willett is a man to watch here. He's coming good later on, but still behind Aldeehani, who remains in front. Kneale and Scott still in the hunt.

Kneale hit only one of his two clays, but Scott took both. Three tied for second now. Remember, four out of six go through....

This is tighter than a wrestler's belt. Fehaid Aldeehani has hit 18 from 20, with four, including Kneale and Scott, on 17. 10 clays left each...

The six men will be whittled down to four - a gold-medal match and a bronze-medal match. At the minute, Kneale lies second, Scott is sixth.

Scrap that, the shooting has caught me off guard. Tim Kneale and Steven Scott are already under way in the semis of the men's double trap. Scott had nailed 10 targets of 10, but has just missed twice. 10 out of 12 for him. Kneale is joint-second with 12 from 14. 

So, disappointment in the women's 4x200m relay, but that's a fairly good return for GB in Wednesday's first session in the pool. 

If you missed it earlier, Chloe Tutton and Molly Renshaw are through to the semi-finals of the women's 200m breaststroke at 03:11 BST as the fourth and fifth fastest qualifiers.

Dan Wallace and Ieuan Lloyd have qualified 11th and 15th fastest for the tonight's semi-finals of the men's 200m individual medley at 03:29 BST.
