The court has been hearing about the interviews Dan Evans agreed to give to officers from the Serious Organised Crime and Police Act in July 2012.
Before three days of interviews he was told "we are not offering you a contract, we cannot offer any guarantees....we are not making you any promises what we really want is the truth."
But the jury heard that Evans agreeing to give the police full disclosure "didn't achieve desired result".
The police asked for a further interview and Evans agreed that he hoped this meant immunity under section 71 was "still on the cards".
"You were willing to do just about anything to get your section 71 immunity weren't you?" Mr Langdale said.
Evans replied: "I was prepared to do anything to move forward in the situation I was in, yes."
He admitted to his solicitor at this time (July 2012) that "full immunity is the only thing I am after."
