England with not too many worries off 14 overs, going quite nicely.

Root knocking it about, Alex Hales being the more dominant partner. Just got to keep cool England and slowly go about their business.

Joe Root hardly looks like he puts any effort in to his shots as he punches the ball to the boundary off Soumya Sarkar.

Mossadek flights one up to tempt Joe Root, but he's not going to fall for that. These two heading for half centuries.

Bangladesh switch it up, with Mossadek Hossain into the attack. Off spin.

They are trying to frustrate England, not much emphasis on attack from them. England content to pick up the singles where they can though.

If you're going to bowl medium pace and you're a part time bowler at least bowl on the off side. Too easy for Root.

Class. Joe Root leans on a medium paced delivery and clips away for four. By the book.

Root then cuts hard but it's well stopped at point. Very well stopped. Four more! Part-time bowler Soumya Sarkar drifts down the leg side and he's punished.

A close up of Mustafizur Rahman's action is fascinating to see. He really is bowling leg breaks at 82 mph. Bizarre grip and action.

Danny O'Brien: Love England's aggressive style of play, but they (esp Roy) need to remember you can actually bat sensibly from time to time.

Steve Jones: How much longer before Jonny Bairstow tells ECB to shove their central contract to play for Yorkshire and in franchise cricket?

Joe Root has signalled to the dressing room but nobody has appeared with a new bat for him as yet. He picks up a single with his current blade.

The 50 partnership is up, from 53 balls.

I've found myself at the top of the Vauxhall Stand, second tier. I'm not sure there's a nicer spot to watch international cricket in England. Padded seats no less, queue-less bar, view that feels like you're on top of the action. Alex Hales could probably hit it up here too.

It's a game of singles and rotating the strike for England at the moment. They are doing that well so far. Joe Root has broken his bat somehow nurdling a single into the leg side.

Opening batsman Soumya Sarkar is on to bowl next, as the keeper stands up. Alex Hales helps himself to an easy single.

Nothing too unusual in Mustafizur Rahman's opening over. I feel a bit let down to be honest.

I'm still surprised about Jason Roy's shot. I'm amazed there wasn't a little man on his shoulder, telling him not to do it.

Alex Hales with a one bounce four, powering Shakib Al Hasan over midwicket.

Here comes the exciting Mustafizur Rahman! We've been told that he bowls all sorts - an 80mph spinner he was described as earlier!

A mix and match bowler. Left-armer, Joe Root gets away from strike as soon as he can. Alex Hales then plays a gem of a shot square of the wicket for four. Cracker.

That brings up England's 50.

Mortaza walks back to his mark looking like he's got rocks in his boots. It must be because of his constant stream of injury problems during his career.

Four! Alex Hales doesn't time his straight drive as well as that video of Joe Root but it's four.

Take a look at Joe Root's silky drive from earlier. Lovely!

England are well ahead of Bangladesh's score at this stage - but they started very slowly indeed. Bangladesh will be delighted with the early strike but they'll also know that these two could take the game away from them very quickly.
