Danny Wilson, a former Wales rugby union international, has told Giggs to take responsibility for his actions, which led to his brother Rhodri and partner Natasha getting divorced.
Rhodri, 36, has vowed never to forgive his brother for his affair, which was just one of infamous relationships the Welshman had, including one with former Miss Wales Imogen Thomas.

‘That is why he behaves in the way that he does. You can’t knock him for his career — what he has done on the field is amazing.
‘He is my son. The door is always open. But he needs to take responsibility for what he did to his brother and his brother’s family.
‘Please, Ryan, call your brother.’
