Oxford trainer Michael Peterson, who is quitting the sport at the end of May, faces two serious GBGB disciplinary charges, writes John Gaisford.

Peterson, 28, attached to both Oxford and Hall Green, has been told that Buckfast Kid at Romford on February 24, and Babette at Hall Green on March 5 tested positive for the beta-blocker Timolol.

Buckfast Kid finished sixth behind Rio Torino in a 400m open, beaten more than 17 lengths, and Babette also trailed in last, beaten almost 15 lengths behind Longest Run in an A6.
