Sorry, Not A boffin
I will not start trading "lies and statistics".
It does not matter how the spreadsheet is frigged, the "UK Carrier group" is not appropriate to the UK political/financial/defence realities in a post brexit world. So, please don't start telling me how little it costs, it was only ever a sop to Scottish voters and retired Admirals. Believe me, as soon as Madam May realises that she needs EVERY PENNY in the BOE to keep her job, those boats are scrap.
We are not talking " I like boats" here, we are talking UK financial reality 2020!
