Savannah Marshall’s bid to become Britain’s first female undisputed world champion was ended by old foe Claressa Shields on points at London’s O2.

In what was the culmination of a simmering decade-long rivalry, American Shields avenged her only career defeat, at the hands of Marshall in their amateur days back in 2012.
