World Athletics Championships live: Updates, times and results with Max Burgin and Matt Hudson-Smith in action

Meziane and Crestan from that heat, in fourth and fifth, move into the top two spots of the next-best three. Australia’s Peter Bol has been nudged down to third and faces a nervy wait for this last heat.

Max Burgin is one for running from the front and he makes his way forward speedily, latching onto the shoulder of Botswana’s Masalela, with Crestan just behind him. This is by far the quickest heat so far.

Burgin looks pretty cool, has a glance up to the screen and moves forward with around 650m to go… he holds on to win from Masalela, with Anderson of Jamaica putting in a good charge down the final straight for third.

Max Burgin, the third-fastest man in British history, is in this next heat. He was an outstanding junior, a former under-18 European champion among other accolades, before a bad couple of years with injury and now at 23 he’s a strong contender.

Olympic champion Emmanuel Wanyonyi is the hot favourite in heat five. Japanese teenager Ko Ochiai will no doubt get the crowd cheering; he looks very nervous, bless him.

Canada’s Hassan gets a yellow card for a bit of a wobble on the start line. Only a caution for improper behaviour, but it feels a bit harsh. If you get two in one tournament, you get the axe.

Wanyonyi hits the front but coming into the final lap Tobias Gronstad of Norway cuts across him, there’s a lot of movement here and now Gouaned pushes through to the front and now they’re all strung out at a very speedy pace! Wanyonyi cruises to the win from Italy’s Francesco Pernici and Ireland’s Mark English.

Ireland’s McPhillips wins heat four from Hoppel (the sixth-fastest man in the world this year) and Taylor, with the winning time 1:44.91.

BBC Sport has a chat with Pattison and asks whether he planned to lead that heat from the front.

“No, not at all, [the plan] was kind of get into a good position, my coaches said 300 in you need to stay alert. I got to the front and felt great, gradually slowed it down, made sure I wasn’t going to get boxed in. The Polish guy came across in front of me and I thought I’ve got to go. Warming up was the best I’ve felt in a long time. Confidence is high after that race.

“I feel like a lot of people who’ve had the year I’ve had would just be happy to be here, but I’ve got a job to do, I’ve got a medal to defend, that’s the goal.” Pattison picked up bronze in Budapest.

He had a word with Lutkenhaus at the end there and is asked what he said. “I said to him I saw 2008 [Lutkenhaus’ birth year] on the start list and was almost sick! I’m just glad I didn’t get smoked by a 16-year-old, he’s had a great season. Fair play to him.”

Steve Cram, speaking on BBC TV commentary, has this to say about the debacle over Hocker’s disqualification in the men’s 1500m.

“There was a counter-appeal and a petition. I think they were going to get Donald Trump involved, it was straight forward, you can’t do that. In the home straight, if you try to jostle, the referee will disqualify you. It’s a bit of panic from the Olympic champion, you could argue it’s not much, but going at speed, it’s momentum, using your arms like that, sadly for him, it was always going to happen. There will be 14 in the final. It’s going to be a bit rough out there.”

I’m not sure the US federation were going to get Trump involved, to be honest. I think he’s got bigger fish to fry.

Pattison plants himself at the front to lead this one from the start. Lutkenhaus is way wide in lane three on the track…. Wyderka of Poland takes the lead on this final lap and wins comfortably, with Pattison holding on for second ahead of France’s Tual.

16-year-old Lutkenhaus finishes seventh of nine, that’s quite a surprise, just left himself with too much to do.

Defending champion Arop was lucky to get away with that, under pressure from Chapple, because his time wouldn’t have been enough for one of the next-best three slots.

The third heat is underway: Ben Pattison is in here for GB, with Cooper Lutkenhaus of the USA the one to watch.

Spains’ Attaoui and Arop of Canada are the ones to watch in this heat.

GB’s Crorken only squeaked into qualifying but he sets off well before settling into the middle of the pack. Arop nudges into the back before smoothly working his way up to the front with around 300m to go, he’s alongside Loti, and Crorken is falling back now.

Attaoui powers down the final straight and wins with ease, from Loti, and Arop, from looking so strong, just about makes it into the final qualifying spot! Crorken fifth in the end and sadly that won’t be enough to make it into the three next best.
