Tommy Robinson claims the man he punched to the ground before the England game last night confronted him twice before he lashed out.
The far right extremist says he was with his wife in Portugal when the England fan came up to him.
He claims he warned the victim’s friends to keep him away.
Footage emerged this morning showing the EDL founder flooring the man with a vicious right hook.
No women are visible in the footage and Robinson claims he sent his wife away before delivering the punch.

In the video which was first published by Mirror Online , one man puts his arm around Robinson before raising his fist to the air.
As an inaudible exchange between two groups appears to intensify, the 36-year-old walks towards a fan and lands a blow to his face.
The man punched by Robinson can be seen lying on the ground wearing an England away shirt, struggling to get up as his pals come to his aid.
Another man approaches Robinson and says: “There’s no need for that, is there?”
A voice, thought to be Robinson’s, responds: “You’ll get knocked out again bruv.”
After a pause of a few seconds, a man says: “F*** about again, you’ll get knocked out again bruv.”
Other supporters can be heard shouting: “Go on Tommy lad.”
Some people can then be heard asking for a picture with Robinson.
There was no mention of Robinson’s wife in earlier videos taken by the failed MEP candidate.
And when he was filmed at Stansted Airport before flying out for the game it appears he was on his own.
