Nazanin Zaghari-Ratcliffe had been in solitary confinement for months, separated from her husband and daughter, when her Iranian jailors provided a rare glimmer of joy.

In July 2016, after months without books or newspapers, she was granted access to a TV with two channels - one showing Iranian soaps, the other Wimbledon tennis matches.

She watched as Andy Murray secured his second Wimbledon title on Centre Court - more than 3,000 miles from her prison cell, but just a little over an hour on the Tube from her home in north London.

Earlier this month the pair met at the National Tennis Centre.
