Ladies ladies! Before everyone goes potty running around with their hair on fire.
Every responsible country puts together contingency plans for the "just in case" scenario.
Quite naturally with the large increase in expats over the recent past another look at what would be needed if/should anything kick off is sensible.
Now with the stated number of 100k uk citizens ( actually subjects but thats another story!!) being, I would think, somewhat on the low side. Could this be a bid by HMG and the IRS to find out where you are as a preliminary to a similiar tax system to our US cousins??
Just a thought as normally the evacuation plans are kept hush hush to stop any interference from less friendly parties.
Or am I being paranoid
