Steven Woolfe has offered a "hand of friendship" to Mike Hookem after an altercation that went "too far," according to Ukip MEP Nathan Gill.
Woolfe was taken to hospital yesterday after what was described as an "altercation" between Ukip MEPs in the European Parliament in Strasbourg.
At one stage it was reported that Woolfe was in a critical condition, suffering bleeding on the brain. However he is now reported to be recovering in hospital.
Woolfe has alleged that Hookem hit him after misinterpreting his suggestion they step aside to resolve an argument. However Hookem denies this, saying he never threw a punch and didn't see Woolfe fall.
Earlier, the Ukip chairman said it might be difficult to get to the truth of the matter, as it appears there were only two witnesses to the incident.
The clash comes at the end of a difficult week for Ukip, following the resignation of Diane James as leader on Tuesday. James stepped down after just 18 days in charge.
Woolfe put himself forward for the leadership contest on Wednesday, and was installed as the favourite before yesterday's incident.
