One GP 'left' a tape recorder on in a room ( a la Good Wife) and recorded - "the other side" yakking and he retrieved the tape later. He had it transcribed and circulated to "his side". And one of his side later waved it in the employers face and said 'ya ya, you're lying'
and there was a lot of ya-ya in court, employment court, and GMC, complaints dept, you've been famed and so on and on
