So, victory for Great Britain!

Leon Smith's side have won the tie and are through to the second round of qualifying which will take place in September - against either Australia or Ecuador.

But to keep up Davis Cup formalities, Jacob Fearnley will be out on court shortly to face Nicolai Budkov Kjaer.

Thanks for joining us!

You've got to give credit to Viktor Durasovic and Nicolai Budkov Kjaer there. Ranked 491st and 1187th in doubles respectively, and they gave Wimbledon champions Lloyd Glasspool and Julian Cash a great run for their money.

And here's Lloyd Glasspool: "It's incredible. We can barely hear you because our support is so loud. Incredible to have them behind us. In the difficult moments they have our backs the whole time and it really, really helps."

On whether their experience together pulled them through in the end: "It helps. We have a good game plan, we've won a lot of tie-breaks, we back ourselves in the tie-break. We weren't panicking and we are double guys, we've been there many more times than those guys have so we back ourselves in those situations."

Here's what Great Britain's Julian Cash had to say after that tense victory: "Unbelievable to play on this court, so nice having this support away from home. It feels like we are at home so thanks to them for getting us across the line. It means the world to get our first point and win the tie for GB.

On whether it was a surprise the match was so difficult: "No, not at all. Davis Cup is very special for that. When people play for their country, especially at home, anything can happen. We were ready for everything, we never take for granted that a match is going to be easy and we're happy to get it across the line."

So that's Great Britain through to round two of Davis Cup qualifying.

They will face either Australia or Ecuador for a spot at November's Davis Cup Finals in Italy.

Neither the British pair or the Norwegians were sure if the match was over, and they all had to look over to the umpire to confirm whether it was a seven-point or 10-point tie-break.

Luckily for Julian Cash and Lloyd Glasspool, it was only seven.

Brilliant from Julian Cash! The Briton volleys it into the feet of Viktor Durasovic and it's match point!

Can the British pair put this tie to bed?

Oh dear. Viktor Durasovic leaps into that backhand and all of a sudden, Great Britain's mini-break is gone.

Perfect precision by Nicolai Budkov Kjaer, who punches the corner of the court with a brilliant forehand to pull a point back.

Two misses from Norway. Advantage, Great Britain.

We're going to a tie-break! An impeccable service game from Viktor Durasovic left the British pair with no hope.

Two enormous smashes from Julian Cash see the Brits through another service game. Now it's up to Norway to hold serve and force a tie-break.

It's all getting a bit tense...

Nerves of steel from the Norway duo. An ace from Nicolai Budkov Kjaer, followed by a volley winner by Viktor Durasovic.

Lloyd Glasspool finds the fence before Julian Cash fires long and we're back level at 5-5 in the decider.

The British pair quickly forget the two missed break points and rattle through yet another love hold on Lloyd Glasspool's serve.

Now would be the perfect time to get some more break points and convert them.

The Norwegians survive! Julian Cash and Lloyd Glasspool think Nicolai Budkov Kjaer has gone long, but it pinches the baseline and they're unable to react quick enough to fire the ball back.

That's a huge hold for the hosts.

Ah unlucky! The net cord clips Julian Cash's shot out wide and Lloyd Glasspool sends the second break point into the net. Deuce.

Here we go! Two big, big chances for Julian Cash and Lloyd Glasspool to break and serve for the match.

It was Julian Cash's serve that let the British duo down in the last set, but can they get through this one safely?

Yes they can! An ace sees them hold to 15 and move slightly ahead.

Nicolai Budkov Kjaer shakes his fist in celebration and lets out a huge roar as Norway battle back from 0-30 down to get the hold over the line and stay on serve in the decider.
