Ollie Robinson continues wide of the crease and hits Pat Cummins on the pad. There's a half-hearted appeal but he knows deep down it's missing leg stump.

Australia run a leg bye.

The final ball of Robinson's over is short and Lyon attempts to hook it, but swishes at thin air.

Jack Rule: I literally have not stopped rocking for the last 20 minutes!! I’m beginning to get sea sick!!

Ian McCormack: Need a new F5 button on keyboard!

NewboldOne: Absolutely riveting! A five-day game with bat and ball comes down to this.

Angled delivery from Ollie Robinson almost slips off the back of Nathan Lyon's bat and Australia scramble another single.

We're nearly down to single figures now. A couple of big hits and it will be curtains for England.

Where are these two wickets coming from? Ben Stokes tinkers with his field. Two balls left in this Robinson over.

Inky: Amazing from Australia. They have shown nerves of steel. Baz/Stokes will be regretting the early declaration if they can hold out.

James Lowe: Be a shame if the only team that went for the win loses.

Daniel Gibson: Couldn’t watch end of Edgbaston 2005 so off to feed the dogs. Thank me later!

Ollie Robinson hits Nathan Lyon in the midriff after the Aussie spinner attempts to pull it.

No run.

Fenners: Get Jimmy on!

Paolo: Thrilling finish at Edgbaston. Surely England will take one more wicket to create a cliffhanger…

Stuart Broad is whipping up the crowd now. Like a conductor at the Last Night of the Proms.

Lots of chin stroking and nail biting as Stuart Broad, legs pumping, bounds in.

He beats Nathan Lyon's bat yet again, and then stoops down hands on his knees.

Lyon works the final ball of his over neatly off his pads for a single. There's a quiet confidence in the Australian dressing room.

Peter: I feel sick.

Christian Evans: Can’t watch, can’t not watch…come on England.

Tom Berry: Can we bring in Simon Jones?

Adam: So many missed opportunities in this game, England will be gutted if they lose - and it's looking increasingly likely!

Nathan Lyon has played straight and calmly.

Australia's last man Josh Hazlewood is nervously jogging on the spot in the dressing room.

Pat Cummins blocks the first ball of Stuart Broad's latest over then pushes forward to nudge a single to bring Nathan Lyon back on strike.

Tense. Dramatic. Brilliant.

Australia need 16 to win. England need two wickets.

Kevin Ticehurst: Test cricket will never die, this is what we play the game for.

Matt Fuery: I don't know if I can do this four more times this summer, I've no nails left already!

BookishSam: Can't cope with this

Zak Crawley did the hard work getting round but then slid with his feet instead of his body.

Oh dear. Zak Crawley makes a bit of a mess of a sliding stop on the boundary after a drive from Pat Cummins off Ollie Robinson and it's four more to the Australia total.

Update on the lady next to me: she’s rearranging her wallet. I think it’s the nerves.

Pat Cummins leans forward and pushes the first ball of Ollie Robinson's latest over for a single through cover. Nathan Lyon back on strike, and he flicks one of his pads for a single.
