Many thanks for your company and happy New Year.
There has been plenty of needle in this match. Eight yellow cards, a sprinkling of controversy yet Anthony Taylor has kept his red cards in his pocket. Plenty for the Match of the Day pundits to get stuck into later.
So close to a second Leicester goal, Ben Chilwell's shot saved by Darren Randolph.
Confirmation that there will be six minutes of additional time.
Leicester fans want the whistle to go...now.
Getting word there will be a minimum six minutes of additional time after Mark Noble's injury.
Leicester are moments away from a first clean sheet in 12 Premier League games - and three crucial points.
Chance for West Ham. Andy Carroll rises high at the far post but his header flies a couple of yards wide of the upright.
Leicester's final change sees goalscorer Islam Slimani replaced by Leonardo Ulloa.
Slaven Bilic will be scratching his head. West Ham have had 22 shots. They have no goals to show for it.
Leicester eat up another few seconds as the impressive Demarai Gray walks off to applause to be replaced by Shinji Okazaki.
Just over 10 minutes of normal time remaining. If scores across the Premier League stay as they are, Leicester will move six points clear of the relegation zone.
That's a ridiculous challenge by Havard Nordtveit, whose studs land in the stomach of Ben Chilwell. Kasper Schemeichel comes racing off his line demanding the referee takes immediate action. Nordtveit and Schmeichel are both booked. Chilwell is able to continue.
Standing ovation for Riyad Mahrez as he is replaced by Christian Fuchs. That's a pretty defensive move by Claudio Ranieri with Leicester still needing a second goal to calm nerves.
Great save by Kasper Schemeichel as Aaron Creswell's low free-kick comes off Ben Chilwell and is heading for the net before the Dane stretches to push it away. That noise you can hear is Leicester's fans biting their nails.
Andre Ayew's 2016 is over. Sofiane Feghouli replaces him with West Ham bossing possession. Leicester need a second goal but there has been little sign of one this half.
Another West Ham change coming up.
Islam Slimani crashes to the ground after Angelo Ogbonna cuts across the Leicester forward just outside the West Ham area. Ogbonna has already been booked and Leicester want a free-kick. Anthony Taylor waves play on.
We've not seen too much of Andy Carroll but the ball almost runs kindly for the big striker inside the Leicester area. After an incident-packed first half, this has turned rather scrappy.
There's frantic activity on the West Ham bench. Here comes the first change.
Mark Noble is unable to continue after that nasty challenge by Daniel Amartey and on comes Manuel Lanzini.
West Ham have work to do if they are to keep their winning run going. They've enjoyed a decent spell of possession since the restart but haven't done much with it.
A corner to the Hammers. Dimitri Payet fizzes it in but it is easily cleared.
It's been a slow start to the new half - not helped by a lengthy stoppage for Noble's injury. It takes a lot to keep the West Ham skipper down and he is back on his feet. No changes so far.
There's a lengthy delay as Mark Noble receives treatment for a nasty whack on the knee from Daniel Amartey. That looked dangerously high by the Leicester man and he is rightly shown a yellow card.
As it stands, Leicester are six points above the relegation zone. West Ham have gone from 11th to 13th. Will it stay like that?
We're back under way.
BBC World Service
Three Premier League players have been named in Algeria's 23-man squad for the Africa Cup of Nations.
But there's good news for West Ham United. Their attacking midfielder Sofiane Feghouli - who was expected to be picked - has been left out.
The three selected England-based players are Riyad Mahrez and Islam Slimani from Leicester City, as well as Watford’s Adlene Guediora.
This is a cracker. Leicester deservedly lead but West Ham are far from out of it.
You can't take your eyes off this.
Angelo Ogbonna is booked for a foul just outside his area on Demarai Gray. Up steps Riyad Mahrez and his free-kick is kept out at full stretch by Darren Randolph.
Drama at both ends.
Havard Nordtveit denies Islam Slimani a second goal with a crucial challenge following Marc Albrighton's cross.
West Ham counter, Robert Huth is booked for a foul on Dimitri Payet, who picks himself up and forces Kasper Schmeichel into a save from the set-piece.
How did that stay out?
West Ham are on top for the first time and Michail Antonio cracks an effort against Kasper Schmeichel's bar.
Leicester, all of a sudden, want the half-time whistle.
Incredible scenes inside the Leicester penalty area. Kasper Schmeichel uses his legs to keep out Dimitri Payet's low angled attempt and the rebound just won't fall for Andre Ayew. Much more promising from the Hammers.
No bookings so far but Winston Reid can count himself fortunate to avoid a yellow card after hacking at Riyad Mahrez's heels. Moments later Daniel Amartey clatters into Dimitri Payet. How long until Anthony Taylor's patience snaps.
Danny Drinkwater is loving this. His driving midfield runs are causing West Ham problems. He was also involved in the move for the goal. This must be the best Leicester have played for some time.
West Ham have hardly threatened as we reach the half-hour mark. They've actually had more shots than Leicester but the Hammers are powder-puff. It's just not happening for them.
Riyad Mahrez certainly looks fresher after his unexpected Boxing Day rest. He's chasing absolutely everything. Marc Albrighton's crosses are causing the visitors major problems while Islam Slimani is at his dangerous best.
An excellent goal from Leicester which started with Riyad Mahrez winning possession and finished with Islam Slimani expertly steering home Marc Albrighton's pinpoint cross.
Trouble is brewing for West Ham.
Not only are they behind but Andre Ayew appears to be gesturing at his own manager Slaven Bilic. Ayew appears unhappy and is waving his arms around. He's hardly been in this game.
Hull City defender on Final Score
That was a classic striker's finish, headed back across the keeper. Textbook from Islam Slimani.
It's been coming from the first minute and now Leicester have the lead they thoroughly deserve.
Another wonderful looping cross by Marc Albrighton again finds Islam Slimani, whose strong header is too powerful for Darren Randolph.
Another excellent Leicester move almost results in the breakthrough. It's all about Demarai Gray's pace as he times his run to perfection before getting behind the Hammers defence and delivering a cross which is just over the head of Riyad Mahrez.
Lots of noise from the home fans. They'll be pleased with what they have seen. Leicester have won just four league games in 2016-17, but they're up for this.
Seven shots already and we have not even reached 15 minutes.
First serious chance for the Hammers.
Wes Morgan just manages to get his head to Aaron Cresswell's cross but the ball falls invitingly for Michail Antonio, who can't keep his shot down.
This is developing into a cracking game already.
