Sprinter Sean Safo-Antwi has been granted permission to switch allegiance from Great Britain to Ghana with immediate effect.
The 25-year-old won the Glasgow Indoor Grand Prix over 60m and finished third at the British Championship last month.
However, having asked for a transfer in January, the International Association of Athletics Federations has now sanctioned the switch.
Safo-Antwi has recently been a member of the Enfield & Haringey club.
