Alan Turing's treatment 'still unbelievable to us'

Gay and bisexual men convicted of now-abolished sexual offences in England and Wales are to receive posthumous pardons, the government has announced.

It follows the pardoning of World War Two code-breaker Alan Turing for gross indecency in 2013.

The great-niece of Alan Turing, Rachel Barnes, tells the Today programme how she felt when Turing was pardoned and how she subsequently campaigned for more pardons.
