That's all from us on a dramatic afternoon in west Wales.

A win that will live long in the memory for Scarlets who are off the bottom of the table with their last-gasp victory.

Ulster will wonder how they managed to let that one slip from their grasp.

Leading with the clock in the red, having two tries chalked off, and even kicking the ball into the stands thinking they had it won...they'll be sick heading back to Belfast.

You can read the match report here while there'll be more reaction to come across the BBC Sport website.

Thanks for joining us!

Scarlets director of rugby Nigel Davies speaking to Premier Sports: "We had a tough second half, but we defended fantastically for long periods.

"These guys are capable and when they get opportunities they can score tries like that.

"They were brave and they've given hope to west Wales.

"You've got to have a good defence and [defence coach] Jared Payne is doing a fantastic job. I've been hugely impressed by him."

Ulster captain Iain Henderson speaking to Premier Sports: "We should have finished it out.

"We let it slip, we let opportunities slide that we should have taken.

"We felt Scarlets position in the league didn't do them justice, but they put in a hell of a performance.

"Fair play to them, they played the conditions well and their defence was really good too."

Nathan Doak speaking to Premier Sports: "Unbelievably gutting. It's very frustrating standing here

"We want to push on so we need to look at ourselves and use this to get better.

"We should have won that game, we won't shy away from that."

It was Mee who gave up the penalty that put Ulster back in front.

What a swing in just a matter of minutes.

South African wing Kok is sent to the bin for whatever is left of this one.

Scarlets have the penalty midway in their own half.

Another good nudge from Costelow brings them 10 metres into Ulster's half.

Some drama here.

Oh my goodness! How close were Scarlets to winning this one?

David McCann races back to make a try-saving tackle and Doak boots into the stands.

It's not over, though, as we go all the way back to check a high tackle from Werner Kok.

Well, that's some of the ground made up.

Scrum penalty and Scarlets go up the line.

Just outside their 22 now...

Clock in the red, Scarlets with the ball but virtually the length of the pitch to go.

Last chance saloon stuff.

Ulster in the Scarlets' 22 seeking what would be a four-try bonus remember.

The hosts need the ball back sharpish if they're to turn this around again.

Scarlets are back up to 15 but Ulster have the ball.

Just three minutes to go as we break for Hume to get some treatment.

Oh, another twist!

James Hume wins the turnover at the breakdown and now Nathan Doak steps up with the tee...

On his 100th Ulster appearance, the scrum half certainly takes his time but adds the crucial three points.

They may still be a man down but back in the lead, Scarlets have forced Ulster back into their own 22.

With about six minutes to go, Ulster will need to get right up the other end to turn this one around again.

What an earth has Sam Costelow got in those yellow boots?

Not only did he make that penalty into the stiff Llanelli wind, he absolutely nailed it.

Somehow, somehow, Scarlets are leading.

Having waited so long to get into the lead, Ulster give it straight back.

All credit to Sam Costelow, though, who steps up and nails a penalty right into the teeth of the stiff wind.

Some kick and this one takes another turn.

It's been 25 minutes of consistent pressure from Ulster in this second half.

They've had more than 60% possession and now they have the numerical advantage too.

Still, though, Scarlets have the lead.

Scarlets have been giving away too many penalties and it's Taine Plumtree who is left to carry the can.

The flanker sent to the bin after an accumulation of offences from his side.

Running out of new ways to say Ulster are going to the corner...
