Given that the mandatory sentence for murder is life, there is little benefit of entering a not guilty plea because they are never going to get a significant discount. They have the right to put the prosecution to proof.
I have no idea what their defences are likely to be, but it is not beyond the realms of possibility that there will be a duress or diminished responsibility type argument. Who knows? Could be just as Rocky says.
And before anyone jumps on the "it's the pond dwelling lawyers' fault" bandwagon, if their instructions are to plead "not guilty", the lawyers have absolutely no choice but to run a "not guilty" trial as per instructions, irrespective that that may fly in the face of legal advice.
