Thank you for the clarification re the status of the RNLI, I am aware of it's 'charitable' status ... and its many faults.
I had not intended to imply that it was a Government asset.
I had hoped to draw attention to the word 'National' in the organisations which currently serve all of the UK.
And 'national', when/if Scotland declared UDI and would still need to have the services of those 'National' organisations.
Cheers
