The defendant said he thought Rahman was "a bit odd" when he met him during Ramadan in 2015, while Mr Vaughan told jurors he 'has been described as paranoid at times by various people'.

Aziz said: "He would say remarks like 'oh, we shouldn't talk about MI5', things like that, 'you don't know who's listening to your conversations'.

"You could just be talking about general stuff, Syria or the infighting between Isis and Al Qaeda.

"He didn't trust phones, he just generally didn't trust mobile phones."

Aziz said he also turned down the chance to work with counter terror officers after police raided his home in Stoke and seized his family's electronic devices during a search in January last year.

"They took my sister's laptop, my mum's phone, dad's phone, they took everything that there was connected to the internet," he added.

When Aziz attended a police station in February 2016 to get his property back after it had been analysed "police wanted to engage with him to assess his stance on Islam", the court heard.

"Aziz spoke of his moderate take on Islam and his desire to be a good father and son," said Mr Vaughan.
