Team GB Celebrate Eventing Silver
Great Britain's eventing team - including a Dorset star - have won silver at the Olympics.
Tina Cook, William Fox-Pitt from Sturminster Newton, Mary King, Zara Phillips and Nicola Wilson finished just five points behind Germany in the standings.
Zara was cheered on by her royal cousins the Duke and Duchess of Cambridge.
31-year-old, who was also watched by her mother again, said the crowd gave her a boost as she competed.
She said: ''It's incredible, it gives you a massive lift as you come into the arena. We're really grateful to everyone who've come here to cheer us on.''
Phillips recovered well after making an initial mistake and knocking a bar down on an early jump on her horse High Kingdom.
She said: ''It was a bit slow in the beginning but after that he got faster, it was my fault, not his. I'm really proud of him.''
She said performing in front of a home crowd did not increase the pressure on her.
''It's the pressure that you put on yourself trying to get the best score you can for your team.''
Monday was the first anniversary of her wedding to rugby player Mike Tindall, but when asked if she had had a chance to celebrate, she laughed and said: ''No.''
Alice Fox-Pitt, wife of William, who watched with her five-year-old son Thomas, gave a massive cheer as Tina Cook completed her round, bringing Team GB their silver medal.
She said her husband was ''ecstatic'' with the result.
''Gold was there for the taking, obviously it's really disappointing that they didn't get it,'' she said.
''It is not Zara's fault there were little mistakes. It's a team, it isn't about one person. William's time faults yesterday were expensive, there's a whole host of reasons - it's never down to one person.''
Mrs Fox-Pitt said the team was still ''thrilled'' with their silver, adding: ''Obviously there's still the individual medals to play for.''
31-year-old Gareth Mills from Shaftesbury admitted December's attack in Ringwood Road in Alderholt.
The 18-year-old woman couldn't remember what happened in Damerham High Street - near Fordingbridge.
The two cases happened in the early hours Cambridge Road and Burnaby Road.
