CJ Ujah has been named in Great Britain’s 4x100m relay squad for next month’s World Athletics Relays in the Bahamas for the first time since returning from a 22-month drugs ban.

Ujah, now 30, tested positive for two banned substances in a test taken at the Tokyo Olympics, which led to his team being stripped of their silver medal.

Team-mate Richard Kilty, who has also been named in the eight-strong men’s squad, said at the time he would “never forgive” Ujah for forcing him to hand back his medal.

Another member of the Tokyo squad, Reece Prescod, is also named despite quitting the relay team shortly before last year’s World Championships in Budapest, and subsequently accusing UK Athletics of “emotional blackmail” in their attempts to convince him otherwise.

Seemingly alluding to the issues relating to Ujah and Prescod, British Athletics head of sprints and relays Darren Campbell said: “They (the men’s 4x100m squad) have had their fair share of challenges in recent years.

“But I have have had my own discussions with each and every member of the squad and know they are motivated, committed and focused on working together to reach Paris.”

Ujah was cleared of deliberately taking a banned substance, but was criticised for not following established protocols when he unknowingly bought a contaminated supplement for £10 off Amazon during lockdown.

Reece Prescod has accused UK Athletics of emotional blackmail after his last-minute exit from Great Britain’s relay squad.

The 27-year-old will not race in the 4×100 metres in Budapest after pulling out on the eve of the World Championships this week.

Prescod claims he was told his reputation would suffer if he walked out of the squad but feels he had no option after suffering a hip injury in relay training three weeks ago.

The 2018 100m European silver medallist also revealed he was told he would not be part of the relay set-up in January, only to get a call asking him to return in July.

“The dust needs to settle for a little bit because some of the conversations that I had weren’t necessarily the most pleasant conversations,” he said, after qualifying for Sunday’s 100m semi-final in 10.14 seconds.

“They weren’t very nice and I was a bit upset about some of the conversations. It just wasn’t a nice environment to be in. I had a few different meetings on occasions and it kind of felt a little bit like emotional blackmail a little bit.

“I was kind of like ‘I don’t want to let down the country’ and they (UKA) were like ‘you know your reputation is going to be ruined if you do this.’

“It’s been quite hard, dealing with all the press and all the negativity. I’ve felt quite isolated at these championships if I’m being honest. I’ve felt quite distant from the team.

“But I’ve just had to say ‘you know what Reece, just get as far as you can in these championships and afterwards sit down with (Stephen) Maguire (technical director).'”

Prescod helped Great Britain to world 4x100m bronze in Eugene last year, just his second major senior medal.

He added: “There was a lot of pressure from the federation. It’s not that I didn’t want to be part of the team. I love the boys but I didn’t want to risk hurting myself.

“If I hurt myself in an exchange three weeks ago, for me to do exactly the same thing might potentially compromise running around the bend. So that was the kind of moral of the whole story.

(It’s come from the) hierarchy, if I am being honest. The other athletes are very supportive.”

Zharnel Hughes, Jona Efoloko, Adam Gemili, Jeremiah Azu and Eugene Amo-Dadzie remain part of the squad. British Athletics declined to comment.

2011 100m World champion Yohan Blake ran a season’s best 10.05 for second in the Men’s 100m at the Ostrava Golden Spike, at the Municipal Stadium, in the Czech Republic, on Tuesday.

The race was won by Great Britain’s Reece Prescod in a personal best 9.93 while fellow British teammate and former Kingston College sprinter Zharnel Hughes was third in the same time as Blake.

Jamaican Tokoyo Olympic finalist Candice McLeod ran a season’s best 50.38 for second in the Women’s 400m behind Poland’s Natalia Kaczmarek who ran a personal best 50.16. Another Polish athlete, Anna Kielbasinska, was third in 50.38, equaling her own personal best.

Puerto Rican Olympic champion Jasmine Camacho-Quinn sped to 12.56 for victory in the Women’s 100m hurdles ahead of Poland’s Pia Skrzyszwoska who ran a personal best 12.65 and the USA’s Nia Ali (12.69).

It was a Caribbean 1-2 in the Men’s Javelin as Grenadian 2019 World Champion Anderson Peters continued his fine form this season with a throw of 87.88m to win ahead of Trinidadian 2012 Olympic Champion Keshorn Walcott (84.77m). Germany’s Julian Weber was third with 83.92m.

Cuba’s Maykel Masso won the Men’s Long Jump with 8.14m ahead of the Czech Republic’s Radek Juska (8.11m) and France’s Augustin Bey (8.00m).
