Wonderful timeline. I just found it yesterday and read it all in a day; looking forward to the general election results...
With the increased British exile population in the Netherlands, I wonder if the Dutch government would have decided to build the Markerwaard polder ITTL. They seriously considered it in reality, and hundreds of thousands of British migrants would strengthen the argument for more land being needed for population relief. If they did, I expect the British exile community in the Netherlands may well have also congregated there thanks to its proximity to Amsterdam and likely plentiful new housing supply.
Countries like the Netherlands and Sweden, with high English-speaking populations and a relatively close proximity to the UK also faced an influx of Brits attempting to illegally immigrate early. The Netherlands especially had a large British exile community during the Junta so many were moving to be with their relatives. As many as 200,000 people of British descent lived in the Netherlands, with one neighborhood of Amsterdam commonly known as “Free London”. Geert Wilders, a Dutch Conservative opposed to EU enlargement had founded a new anti-immigration “Party for Freedom '' especially capitalised on the risk of British and Polish immigration with some polls showing his new party winning as many as 15 seats.
