Custody battle for Rocco described as a 'power fight' between Madonna and Guy Ritchie

Madonna and Guy Ritchie's custody battle over son Rocco is "a power fight" between the pair.

Rocco, 15, walked out of Madonna's 'Rebel Heart' tour in December to stay with his father in London and Guy is said to have hired lawyers as he prepares for a custody fight with his ex but insiders claim the battle is due to their contentious relationship.
