Katie Taylor may be the unbackable favourite to complete her march to Olympic boxing gold at ExCeL tomorrow but her right to reign as the undisputed world number one women’s boxer has been challenged by opponent Sofya Ochigava.

Paddy Barnes hopes to become the first Irish boxer to win two Olympic medals and victory over newcomer, Devendro Singh (India), in tonight’s quarter-final the ExCel (8.45pm) would fulfil that ambition.
