Warwickshire secure their Division One place! 

Rikki Clarke (4-20) ends the Lancashire innings as Kyle Jarvis chips him to Ian Westwood at silly mid-off.

Lancashire are now left waiting on the result at the Ageas Bowl. They need Durham to bat out for the draw or beat Hampshire.

Durham are currently 83-1, chasing 296, with 47 overs left.

Meanwhile, at Edgbaston Arron Lilley is flashing the willow.

He smashes Jeetan Patel for 20 off his 24th over, including three fours and a six.

But it's only a matter of time in this one.

Steve Eskinazi shows Jack Brooks the full face of the bat and strokes him straight down the ground for four. Beautiful shot.

A couple of balls later he whips the headband-wearing warrior through the leg-side for three. This is more like it as drinks come onto the field.

nw5blue: Ironic that the 20/20 format will decide the County Championship title this season.  

Simon Jenkins: Perhaps Middlesex think this is a five-day game.  

Ryan Sidebottom has the shiny new cherry in his hand for Yorkshire.

And the wily left-armer finds some movement straight away, beating Steve Eskinazi with an absolute beauty.

At last a bit of aggression from Steve Eskinazi. The 22-year-old charges Azeem Rafiq and powers him over mid-wicket for four.

Middlesex's lead is 95 - there are 55 overs left. We could still see a chase of 200/220 off 35 overs here. 

Let's hope so.

Chris Davidson: If a winner doesn't come from Lord's both captains should be fired   

Finally, off his 27th delivery, Steve Eskinazi sweeps Azeem Rafiq for a single.

The Somerset players are at Taunton enjoying a bit of lunch. It'll taste pretty good right now - the game at Lord's is going nowhere fast. I'm still confused as to what the gameplan is here.

Middlesex lead by 85 with 57 overs left.

That's swung an absolute mile from David Willey. Dawid Malan just about manages to get some bat on it in front of the timbers.

It's been a pretty quiet opening 15 minutes after lunch. Not what I was expecting.

Okay, I'm really confused about how this afternoon session is going to unfold.

Steve Eskinazi has faced 19 deliveries and still isn't off the mark.

A draw is no good for either side. Why aren't Middlesex just having a go?

Middlesex 270 & 202-3 v Yorkshire 390

Malan skips down the pitch to Azeem Rafiq and pinches a quick single to bring up his third Championship century of the summer.

The 29-year-old Londoner has looked in fine touch with 11 fours in his 203-ball knock.

Will we now see him open his shoulders?

Dawid Malan and Steve Eskinazi make their way to the middle after lunch.

Azeem Rafiq will open up to Malan who's on 99.

This is the session where we'll finally have a better idea of who will be crowned county champions.

What an afternoon we are in for here. Durham were set a target of 296 to win and at lunch they are 41-0. Keaton Jennings needs 81 to beat the club record of 1,601 Championship runs in a season.

He survived a massive appeal for LBW from Will Smith's first ball and is on 14 at the break, while team-mate Mark Stoneman has 27 in his last appearance for the club.

There are 63 overs remaining and Hampshire know with Lancashire in freefall a win for them will keep them up and send The Red Rose down.

It's all to play for but Durham are up for the challenge as well.

Adam Fitzgerald: Definitely a bucket load of strong Somerset Dry Cider on my shopping list. What a great advert for English cricket

Rich Hird: Can't help but feel Somerset fans will be left looking p'Ale and feeling rather Bitter when Yorkshire win the title later

An excellent morning for Gloucestershire who have cleared the arrears and lead by 17 at lunch

Hamish Marshall was applauded to the wicket by the Sussex players on his farewell appearance, and  has batted imperiously, a straight six down the ground being the shot of the morning

The new ball is due in 12 overs and that may well hold the key to the outcome of this match

Lunch here is traditional Chilli Con Carne not sure how it differs from normal Chilli Con Carne, whatever it's very nice!
