Busy with other stuff, but a few points and corrections.
1. Belmarsh (and Cat A generally) is often viewed as a benefit in terms of conditions for prisoners, as the additional security, rules and high risk element means that they have more facilities.
For example, as the regime wants to avoid unnecessary movements within the prison, the statutory entitlements, such as gyms, are localised on each wing.
It is actually the Home Office that wants to incentivise lower classification of prisoners, as the immense cost of Cat A (£100K+pa) compares poorly with the £20K annual cost of Cat C.
2. TR’s civil offence status will be a real headache for a Cat A establishment to administer, as I suspect that it will be the first time they have to apply the status to their regime for some while.
3. If he stays in Belmarsh, it is hard to see how his HDC (Tag) can be processed, as technically under HDC, you are still in prison, but at home. How that could work from a Cat A (by definition maximum security) is unclear.
4. Release under licence is actually still serving the sentence imposed by the court, but under licence in the community. Therefore it is technically correct to say 9 months prison, etc., etc.
5. For those considering writing to TR, I would suggest the email service emailaprisoner.com (I think), as it’s cheaper and same day receiving in normal circumstances. The only disadvantage of this is that you can’t send an SAE in, which is required for him to write back. This is because there is a limit of expenditure he can make per week and using that up on postage stamps is not a bright idea.
