The worst of starts for Katie Boulter, who gets her first service game under way with a double fault.

But never mind, she redeems herself with two quick aces.

Job done for Leylah Fernandez as Katie Boulter pushes into the net.

Perfect timing from Leylah Fernandez with the ace, saving the break point before landing a forehand down the line.

A classy return from Katie Boulter, pinching the line to bring up an early break point.

A nervy start for Leylah Fernandez, who double-faults to bring Katie Boulter level at 30-30.

The warm-ups and a final team-talk with their captains are complete.

Away we go. Leylah Fernandez serves first to get us started.

On the other side of the draw to Great Britain, the semi-finalists have already been decided.

Iga Swiatek secured back-to-back wins to lead Poland into the last four of the Billie Jean King Cup Finals for the first time.

The world number two levelled the tie at 1-1 against the Czech Republic after defeating Linda Noskova in a match that lasted two hours and 39 minutes.

Swiatek then returned to court with Katarzyna Kawa for a rare doubles encounter, with the pair sealing a 6-1 6-4 win against Katerina Siniakova and Bouzkova.

Poland will face Italy next as Jasmine Paolini helped her side to victory over Japan, also winning her singles and doubles matches.

Here come Katie Boulter and Leylah Fernandez.

A big cheer from the crowd as British number one Boulter arrives on court with a smile on her face and earphones in.

Fernandez walks in with a brief wave and her game face on.

Only six ranking places separate these two.

An iconic tournament like the Billie Jean King Cup needs an iconic trophy.

And here it is!

Perched in the corner of the Malaga court, watching over the action, is the prize which Great Britain hope to be lifting on Wednesday.

The silver vase with its distinctive handles sits on top of three circular tiers which have the names of all the previous winners etched.

Billie Jean King, of course, is among them after several triumphs as a player and captain for the United States.

As always we want to know what you think!

What did you make of Emma Raducanu's performance? Reckon Katie Boulter can make it a clean sweep with victory over Leylah Fernandez?

And are Great Britain strong enough to go all the way?

Let us know your thoughts using the methods above.

On the crowd: "We had some competition with another band but I think we snuck the win! Much appreciated to everyone supporting. Of course, it was an honour to play in front of Billie Jean King herself and Conchita [Martinez]."

On playing in the Billie Jean King Cup: "My Billie Jean King Cup performances have brought very good things out of me and I think it is the same for everyone. We all just fight extra hard, dig in a little bit. It is an honour to be representing my country carrying on and scoring a point and hopefully Boults [Katie Boulter] comes out and does the same."

GB's Emma Raducanu speaking after beating Canada's Rebecca Marino: "It was an incredibly difficult match because the dynamics were so different in each of the sets. In second set, Rebecca really upped her level and serving great, a lot more first serves which made it more difficult to get into her service game. I'm very pleased with how I managed to fend off my own break points and then sneak that break at 5-5 and close it out.

On getting that break: "When you're playing a big serving opponent like Rebecca who is such a big server, you know there is so much emphasis on each serve. It definitely helped to have the support of our band on every single point so thank you."

As you would expect, the Brits are heavily outnumbering their Canadian counterparts on the Costa del Sol.

This lot, part of the 'Barmy Army' which provides the vocal support, are fuelling up for the tie.

Plastic pint pots filled with something which looks suspiciously like tinto de verano - the staple Andalusian summer tipple which is heavy on the red wine and supplemented by soda - fill the table between them.

"You have one, mate. It's blackcurrant," says one of the lads as he lifts a glass in my direction.

Sure it is. Their job - roaring on the Brits over what could several hours - requires a little loosening of the inhibitions than mine. It's a polite decline, of course.

Don't go anywhere! We'll be getting back under way in Malaga very soon with British number one Katie Boulter and Canada's Leylah Fernandez taking to the court in less than five minutes.

Emma Raducanu sped through the first set in 28 minutes, winning six games in a row.

But Rebecca Marino improved drastically and the second set lasted over twice as long at one hour and two minutes.

We'll bring you Raducanu's post-match quotes very shortly...

"Duh-duh-duhhhh Emma Raducanu, dun-duh-duhhhh," chant the British fans.

They're happy. Raducanu is happy. Everyone in Union Jack attire is happy.

Over to Katie Boulter then...

Very impressive, Emma Raducanu almost caught Rebecca Marino cold.

Marino certainly played so much better in the second set. She will regret not converting any of those seven break points.

Credit to Raducanu to hold her nerve out there and be able to close it out.

And there goes the second as Rebecca Marino sends a blistering forehand winner across the court.

One more shot.

Some nerves perhaps? Emma Raducanu double-faults on the first match point.
