A schoolboy has been dubbed the UK's version of three-time Olympic gold medallist Usain Bolt after smashing a national record in just his second race.

The only other time he ran a 400m race, Clovis became Manchester schools champion.

Mum Beatrice Efuet said she was `so proud' to watch her son -a pupil at Our Lady's Sports College in Higher Blackley, Manchester - in his record-breaking run at the championships in Sheffield.

Danny Gray, Clovis's coach at Sale Harriers athletics club, said he could never have predicted the youngster would break the record so easily.

He said: "To watch him cross.....
