Why are they allowed to fight if they do not have licences?

Because European Union freedom of trade laws permit the fight to be held in the United Kingdom and they have been given licences by the Luxembourg Boxing Federation.

"It is a way of dancing around the regulations," said BBC boxing commentator Mike Costello.

Chisora's manager Frank Warren said: "I have legal obligations to Chisora and I won't have these compromised by the British Boxing Board of Control. They said he was able to apply for a licence in another jurisdiction at the hearing and that is what he has done."
