Hello I am a solicitor with 20 years experience. I will try to help you with this.
Just a first point it is illegal to discuss your jury deliberations with anyone outside the jury room so I will will talk in generalities here.
Initially the Judge will only accept a unanimous verdict but after a while he will tell the jury that he will accept a majority verdict. That is a majority of 10-2. The likelihood is that if a juror is alone in his view on any verdict and the rest of the jury are settled in their opinion all they can do by holding out is delay the verdict by a few hours.
Thank you. That's reassuring to know. I fully understand that I cannot discuss details with you so appreciate you taking the time to reply in a general sense.
