The spy found dead in a padlocked holdall hated the 'flash sports bag' and 'leathery confinement' culture of the MI6, according to reports.
Gareth Williams, 31, told his sister, Ceri Subbe, he wanted to leave London because it smelt of rats' piss and was unhappy working for the security services from the inside of a sports bag .

Mr Williams joined MI6 on a three-year secondment from GCHQ in 2009 but after spending the first three months of his probationary period inside the holdall his 'enthusiasm for the job had begun to fade', Mrs Subbe said.
'He disliked MI6 bag culture, post-work bag talk, flash holdall competitions and being stuck next to tennis rackets. He even spoke of breathing difficulties.'
In her oral evidence she added that her brother, a keen cyclist, was a 'country boy and the being padlocked inside a bag 24/7 lifestyle did not quite suit him'.
'Also, I think the job was not quite what he had expected,' she said. 'There was a lot more being confined in holdalls used to carry sports equipment than he was comfortable with, but more than anything he just wanted to get out of that bag and move his legs around a bit.'
