Can I ask you Rob where you got this information from?
I am struggling to remember to be honest where I read this RJ? I do know Rivlin was very poor in his questioning of Bews as it was unbelievably Rivlin who suggested it was a trick of the light.
If I had been JB I would have been furious with Rivlin, he was badly let down in this matter. It was Myall who first spotted possible movement though.
I will try and locate where I read it,
