Commonwealth Games silver medallist Kyle Langford has been named in the British Atheltics' Doha World Championships team, despite a second complaint about his conduct in a matter of weeks.

At the end of June, the 800 metres runner was forced to apologise after he shoved an official at a track meet in Watford following a heated row during his warm-up.

The official had shown Langford, who finished fourth for Great Britain in the men's 800 metres at the 2017 Worlds in London, a red card for warming up too close to the 5,000 metres race that was under way.

The incident was caught on camera and posted on social media, prompting Langford, who is from Watford, to issue his apology, blaming his behaviour on "pre-race tension" and admitting that his "behaviour fell well short of what it should be".

UK Athletics later gave him a written warning, fined him £1,000, which went to charity, and ordered him to do one day of community service within the sport.

And Langford is now facing a second complaint, allegedly related to a clash with fellow runner James McCarthy during the British Championships.

Langford qualified for the final in Birmingham with victory in the heat on August 24 but only after he tangled with McCarthy, who nearly fell and finished seventh. McCarthy appealed to the officials and was given a place in the following day's final.

Langford finished eighth and McCarthy a distant ninth in the race, with an alleged post-race incident reportedly resulting in McCarthy making a formal complaint to UKA, and Langford issuing his own counter-complaint.

The governing body declined to comment but Langford's manager Gary Lough told the PA News Agency "complaints have been made along with a requested investigation into specific incidents and persons".

The first two home runners in the final were guaranteed a spot in Qatar provided they had also run the qualifying time of one minute 45.8 seconds this season, but neither winner Spencer Thomas nor runner-up Guy Learmonth had achieved that feat.
