That's all from us tonight, thanks very much for joining us as Emma Raducanu and Katie Boulter got the job done for Great Britain!

If you missed any of today's action, you can catch up by reading Jonathan Jurejko's report from Malaga right here.

And remember, we'll be back on Sunday to do it all over again as GB take on defending champions Canada for a place in the semi-finals.

That tie is scheduled not before 16:00 GMT and will be live on the BBC Sport website and iPlayer.

See you then!

Here's how Katie Boulter swept aside Laura Siegemund to land Great Britain in the last eight of the Billie Jean King Cup Finals.

With Emma Raducanu and Katie Boulter ranked higher than each of their singles opponents today, Great Britain were considered the favourites against Germany. But where do they rank against the Canadian team?

Boulter is ranked a career high 24th, while Raducanu is currently 58th as she continues her return from an injury-plagued 2023.

Defending champions Canada, who received a bye in the first round, are led by Leylah Fernandez, who is 31st in the world.

Recognise that name? Raducanu won her first Grand Slam by beating Fernandez in the final at the US Open.

Rebecca Marino is Canada's second highest ranked player at 103rd, so once again GB will be considered favourites.

If you missed it earlier, here's how Emma Raducanu - playing her first match in almost two months - put Great Britain ahead before Katie Boulter sealed the deal in the second singles rubber.

GB captain Anne Keothavong on facing quarter-final opponents Canada: "We know Canada are next. Obviously, we are going for the win but we are ever so grateful to all the people who have travelled from the UK to support this team. What we really need is for everyone to come back again on Sunday and help us get through it. Please, please come back!"

GB captain Anne Keothavong: "I'm a very proud captain. It was a fantastic performance from Emma [Raducanu] and Katie [Boulter] this evening. The way they came out.

"For Emma, having been off for a period of time, the way she dealt with everything.

"The way Katie started in this match to get the job done. I couldn't be more proud of them and all the others in the team."

Katie Boulter on the crowd in Malaga: "Honestly it feels like we are in Great Britain right now. Our fans are awesome, you always get behind us in the good moments and the bad moments. You always get behind us. Thanks so much for coming here to Malaga it means so much to all of us players for sure so thank you."

Katie Boulter speaking after sealing Great Britain's place in the last eight: "Obviously I'm thrilled with getting a win for GB today. These matches mean so more than all the other ones because you are playing with the flag on your chest.

"It felt good, Emma [Raducanu] started us off great which was really nice. For me to come out and have a swing at 1-0 up, it felt great so it's been a really good day for us."

After beating Germany 2-0, Great Britain will face defending champions Canada in the quarter-finals.

Canada sealed a 2-0 win over Italy in last year's final in Seville, with Leylah Fernandez and Marina Stakusic, who was ranked 258th at the time, claiming singles victories.

The win earned Canada a record $2.4m (£2.1m) in prize money, one year after the nation won its first Davis Cup.

Katie Boulter needed just 70 minutes to wrap that win up.

The 28-year-old gives captain Anne Keothavong a big hug before bouncing along to give all her team-mates and coaching staff a high five.

Unbelievable performance from Katie Boulter.

Served well, returned well, she just stayed in control of the match.

Boulter moved brilliantly, she just loves this event.

She thrives on it, she's able to deal with the pressure and play her best tennis.

That's what pressure does to you. A double fault from Katie Boulter as she squanders the first match point.

Laura Siegemund fires long. Two match points for Katie Boulter and Great Britain.

A double fault by Katie Boulter chalks off her forehand winner and pulls Laura Siegemund level, but she makes up for it with a brilliant backhand winner that just pinches the line. 30-15.

Laura Siegemund is still in this but she will be feeling so much frustration.

Here we go then. Can Katie Boulter serve it out and send GB into the quarter-finals?

A big forehand winner from the baseline and it's advantage, Laura Siegemund.

The German number one gets the holds over the line, putting the pressure back on Boulter to serve out the win for Great Britain.
