It seems as though RAVEC will be meeting to reconsider the security needs of the Sussexes I thought it might be interesting to have a thread to contain discussions about it rather than getting lost in the various other topics.
RAVEC = Royal and VIP Executive Committee
For security reasons the entire make-up of the committee isn't usually disclosed but it's thought to be a ten person committee with members from the Home Office, the Metropolitan Police, the Royal household, National Security Secretariat representing the Cabinet office and Foreign, Commonwealth and Development Office.
It's decisions are informed by the Risk Management Board, a sub committee of police officers, security service officials who conduct the risk management and threat assessments.
The board considers and evaluates threat level, public exposure, public profile, and operational considerations (how proportionate should the response be to the threat identified)
Security provided can be full-time 24/7 armed close protection, event specific, or visit-based cover.
24/7 close protection: currently automatic for monarch and heir and their families, PM, some Cabinet members, former PMs, some MPs and former MPs who had specific jobs which put them at risk.
Event-specific: Other working royals when on official business,
Visit-specific: Foreign heads of state and dignitaries coming to the UK, up until the move this is what Harry was offered (he would tell them he was coming and what his plans were and the Risk Management Board would do a risk assessment and provide security if necessary.)
For the 24/7 close protection - apart from the monarch and heir and the former PMs who are currently protected for life, this protection may only last a specific period of time, for example former Northern Ireland secretaries who might be facing a specific targeted threat for a period of time but are downgraded later into their retirement.
It's estimated the the former PMs get a 15 person team to cover their 24/7 needs at a cost of between £1.2 million and £3 million per former PM annually. (Liz Truss!)
