Tom Bosworth, I'm afraid, has been caught. Not only that, but there was some argy-bargy as the walkers went round a hairpin. If I had to describe the walking, I would call it viscous and wiggly.

What a win for Britain's Chris Langridge and Marcus Ellis.

They have beaten Korean third seeds Kim Gi Jung and Kim Sa Rang 17-21 25-23 21-18.

That's their second match of the event, following defeat earlier, and it brings them right back into contention for a quarter-final place.

That's not the only good news for Britain either...

If a medal from Bosworth would be unexpected, one from the dressage team certainly would not - Great Britain are aiming to retain the title they won in London.

The British quartet for Rio is made up of Spencer Wilton, Fiona Bigwood, Carl Hester and Charlotte Dijardin and they are lying in second at the moment, behind 2014 world champions Germany.

Bigwood, riding Orthilla, has just been in action and she collected a score of 74.384, with Carl Hester and Charlotte Dujardin still to come.

We've reached the halfway stage of the men's walking final and Briton Tom Bosworth, who has never finished in the top 10 in an international event, has a sizable lead at the front, passing the 10k mark in 40 minutes and 10 seconds.

Defending champion Chen Ding is really feeling the pressure as well, grimacing as he struggles along behind the main pack.

Bosworth has been yellow-carded, mind...

So no medal for Amber Hill, but, around Rio, there are two other prospects for Great Britain...

For the first time today Amber Hill allowed her focus to go as she glanced over her shoulder at her family when the shot from Meng Wei confirmed there would be no medal.

Italians here are rejoicing, some arms aloft among the crowd as an all-Italy gold medal match is confirmed. Diana Bacosi is crying, not the reaction you'd expect as she's in the final.

Still, no British woman has ever won an Olympic medal. Italy will pocket two from this event alone.

Ah. That's it. Meng Wei of China takes her final four targets, meaning Hill can finish no higher than fifth. The 18-year-old must wait for Tokyo for her Olympic medal. It will be an all-Italian final.

And the next two! Total score of 13. Now we wait...

Two hit by Hill...

Four targets each remain. I reckon Hill might need to hit the lot of them. Shooters wait in a line. Hill, blue cap, is up next...

It's rare this week but the shooting range in Deodoro is packed for this final.

Amber Hill - just 18 years of age remember - is a little slow off the mark and with just four shots left sits last of the six shooters.

At this stage, sneaking fourth looks her only hope. Such a result would see her in a bronze medal match.

Fourth would be good enough for a place in the bronze medal match. A hit from the Chinese shooter sends her down to fifth...

16 shots each. Top two through to the final. One miss. She has nine out of 12. She sits fourth...

From one medal prospect to another. Amber Hill's skeet semi-final is already under way...

Dave: Yesssssss Andy Murray, ye got to stop doing this to us man!

Fellowhoodlums: Beast @andy_murray

Susan Porter: YES!!!!!! We should never have doubted

Finally! For the second time in two days Andy Murray comes through a final set, keeping the defence of his Olympic crown alive. Murray sees off Steve Johnson and is one match away from another Olympic medal. He will meet either Gael Monfils or Kei Nishikori.  

Johnson drifts wide. Four match points for Andy Murray....

Murray gets the mini-break back when a Johnson drop goes into the net. Two points away.
