Apparently he's lied about the reason too. He claims his house was subject to an arson attack.
1 No such attack has been reported to the police.
2 The house is now in his wife's name (apparently they're about to separate/divorce)
3 He's on the verge of losing a court case and will probably be landed with hefty legal costs, which will be more difficult to get back if he's in Spain.
Spain is welcome to him. Apparently, he's eligible for an Irish passport, which he might or might not have, so he could be an EU citizen. If that's the case, I hope his supporters can see what a hypocrite he is.
