I'm afraid your assumption isn't correct, Shirley....
In this household, as soon as the referendum was announced as happening, in January 2013 I believe, we knew there was a very strong chance we would be leaving the EU. Anyone who has roots in Wales or N England, especially, will know there is a real dis-connect from the rest of UK, the problem being the have's and have-nots. Not just income, but prospects to improve oneself, which has been a gulf widening for years now. To find that people previously 'shut up' by the establishment and elite would finally have a voice, meant that voice would be heard. Nothing to do with being far-right, as most were Labour supporters!
We speeded up our slow plans for eventual return to UK, having already purchased a small foothold back there, by down-sizing here (this year) and moving into a much smaller place to serve as a second home for the future. The income released from that was to be returned to UK to implement money for a permanent home there eventually. All this was done with much stress and difficulty, but to retain control of our own destiny.
So, when we had the funds finally in place, which was before the referendum, we placed our FX order on avo 22nd, at a fixed rate with our broker, advising him the vote will be leave, and the market will de-stabilise for a short while, and may have a crash.....he was rather cockily 'gob-smacked' (a pattern forming?) and we now know why, from the feeding frenzy of the traders who called so wrongly in vast numbers, causing huge de-stabilising, briefly. We now all know the way the democratic vote went, but the rate we fixed was no-where near the hysteric doom and gloom predictions of that very talented George Osborne. In fact the rate, although down a bit now compared to over 3 weeks ago, is in our opinion kept down because of the continued attempts to overturn democracy and keep the uncertainty going, as per on this particular topic of forum!
In our time here we've received 1.46 and 1.1 to sterling, and no doubt the rates will always sway back and forth, but for UK business it is now an opportunity to trade with a weak pound, and this was a vote pertaining to the UK. This result shouldn't have come as a total shock, if folks were taking an all-round view of matters, rather than the limited view presented by the media along with their attempts to link it to fascism, biggotry, racism, etc, still on-going. We all make choices in life and have to live with them. As advised, if people also feel so strongly that France is their forever home, then seeking French nationality, as swiftly as possible, seems obvious to me. Those of us who voted out whilst living here did so also with the hope that residency rights will not be affected for those here, and that all will come good for the EU machine in the future, embracing the UK in an entirely new but better way. It is looking very good so far on both fronts.
