Title hopefuls Surrey go eight points clear at the top of Division One with draw at Northants
Warwickshire hang on for draw with Somerset in key game at bottom of table
Middlesex beat Glamorgan in key game in Division Two promotion race
Durham complete win over Leicestershire
Glamorgan 214 & 204-9, Middlesex 390
Toby Roland-Jones makes the breakthrough at Lord's to get Ajaz Patel.
The lead is still only 28 as Michael Hogan comes in to join Timm van der Gugten.
Leicestershire 202 & 198 v Durham 296 & 78-3
No sooner had Michael Jones brought up his 50 then he is bowled by Chris Wright as a bit of in-swing gets past his attempted booming drive.
Only 27 to win, so surely too little, too late for Leicestershire.
Northants 339 & 232-5 v Surrey 421
Saif Zaib and Ricardo Vasconcelos have quietly accumulated 27 runs in the six overs so far.
Surrey will not be panicking at all, but Northants now lead by 154.
Plenty of work to do to get the win they want.
Sussex 220 & 50-1, Worcestershire 438-5 dec
No early breakthrough yet either for another of the Division Two promotion chasers Worcestershire at Hove.
Sussex opener Ali Orr and nightwatchman Brad Currie have so far added 13 runs this morning to take thr score to 50-1.
Glamorgan 214 & 204-8, Middlesex 390
13 runs this morning so far for Glamorgan's ninth-wicket pair, Timm van der Gugten and Ajaz Patel.
The slender lead is now up to 28.
Leicestershire 202 & 198 v Durham 296 & 68-2
Michael Jones has already stroked two boundaries and two threes this morning as Durham make light work of this chase.
Expect the final 37 runs to arrive quite quickly.
Northants 339 & 217-5 v Surrey 421
The leg spin of Cameron Steel opens at the other end.
We have had 67 overs in this Northants second innings and so there are 13 more until the second new ball.
Captain Rory Burns will probably keep West Indies quick Kemar Roach and new ball partner Dan Worrall back until then.
Somerset 219 & 278-5, Warwickshire 196
Henry Brookes strikes with the fourth ball of the day at Edgbaston.
Lewis Goldsworthy is bowled - and James Rew, out first ball in the first innings, comes in 'on a King Pair', which he survives.
And the next delivery too!
Next up to bowl is spinner Jayant Yadav.
Northants 339 & 211-5 v Surrey 421
Play has begun on the final day at Wantage Road.
Gus Atkinson has the ball, bowling to Saif Zaib. And he starts with a no-ball, adding two to the total.
This week's big game has been the meeting of fourth against second at Lord's - and that seems all but sorted.
Middlesex are almost assured of victory over promotion rivals Glamorgan, who have a slender 15-run lead, with Timm van der Gugten and Ajaz Patel at the crease - and only last man Michael Hogan to come.
It will take a Welsh miracle alongside Scott Gibbs' matchwinning try at Wembley in 1999 to save this one.
Durham are also well on their way to beating winless bottom club Leicestershire.
Set 105 to win, they are 51-2, needing a further 54, as the Foxes face the prospect of a winless season for the first time since 2013.
And, after declaring on 438-5 following a third-session thrash at Hove, 218 in front, Worcestershire have the task of bowling out Sussex, who trail by 179 with nine wickets in hand.

Title-chasing Surrey seem on course for victory against Northamptonshire at Wantage Road - a win that would lift them back to the top of the table, ahead of their only rivals, Hampshire.
Hashim Amla completed his ton, then an emotional Tom Curran struck a superb maiden first-class century on the ground where his late father Kevin once shone.
But the Division One title chasers still need to take five Northants second-innings wickets before embarking on their second innings - and the hosts have already built a 127-run lead.
Image source, Getty ImagesAs for the bottom of the top flight, Somerset took a big step towards retaining their Division One status at the expense of last year's champions Warwickshire.
An unbeaten 91 from George Bartlett and 87 from skipper Tom Abell guided them to a 300-run lead over their fellow strugglers.
Somerset, who began this week seven points better off than the Bears, have so far gained an extra bonus point on them.
But is there more to follow? Will they bat out the game for a safe draw, knowing that the Bears have the opportunity to go to Bristol and win next week against doomed bottom club Gloucestershire?
Or will they declare and try to bowl out their hosts?
Somerset's final two games are at home to Northants, then away to One-Day Cup finalists Kent, who might not yet be out of relegation danger themselves.
Wantage Road: Northamptonshire 339 & 209-5, Surrey 421

The BBC weather national forecast says: "Breezy and bright for many today. Showers in northern and eastern areas. A cool day."
Good job there's no longer a game on in the north then!

Image source, Rex FeaturesWelcome back to the final day of this week's round of County Championship games.
One of the six matches is over, up in Leeds, where Essex's last pair held their nerve to beat Yorkshire by just one wicket in a Headingley thriller.
But we stil have two other Division One games going - and three more in Division Two.
So, at this sad but nonetheless uplifting time of national mourning, thanks for joining us again.
