"Would you like a cup of tea and a sticky bun?" asks Sue Barker on BBC Two. "It looks like we'll be talking for quite some time."
Milk, two sugars, please Sue, very kind of you.

Umbrellas have mushroomed around the arena as the rain thickens and comes down more rapidly. The start of the first rubber has been delayed, though we are yet unsure by how long. Soggy spectators are being treated to a Justin Bieber tune, though, so it's not all bad.

BBC tennis correspondent at WimbledonFriday's first rubber could be critical to the outcome of the tie. Edmund might be ranked 338 places above Janko Tipsarevic, but before a string of injuries the Serb was good enough to qualify for the 2012 World Tour Finals.

In Andy Murray's absence, British number two Kyle Edmund takes on Janko Tipsarevic in the opening rubber.
"Davis Cup weeks are my favourite weeks of the year because these guys are my brothers and my best friends. It won’t be easy because I am playing against a young and upcoming rival but I am really looking forward to it," said Tipsarevic, the world number 405.

It's such a shame about the rain. But this is on a clay court. All depends how heavy the rain is. If it's just some drizzle on clay then it's fine.

According to this satellite image, it appears that play in Belgrade might be interrupted because of heavy storms. Let's hope the forecast is wrong, wrong, wrong.

Murray cheering from the sidelinespublished at 14:45 British Summer Time 15 July 2016
Hello! Welcome to live coverage of this Davis Cup quarter-final between Britain and Serbia.
Serbia are the hosts, have chosen to play on red dirt and will fancy their chances of seeing off a visiting team which only has Wimbledon champion Andy Murray as a vocal supporter.
The British number one has traveled eastwards with his team-mates but we will not see him hitting a sweet volley or a cracking forehand.
“I am not here to coach any of the guys, just try to help where I can," says Murray. "I’m not going to start telling anybody what to do. If anyone wants to ask me anything I will try and help wherever I can and just support the team.”

The world's best player has opted to sit this one out, as has the second best player in the world. Should we still be interested? Of course.
Britain, the reigning champions, the history-makers, begin their bid to retain the title they spectacularly won last November. Can they successfully defend their title? The odds are against them as they take on Serbia in Belgrade.
