Hi Bornatbirth, not sure if your qustion was for or Darren.In my case I actually did a personal SWOT analysis and reckoned that fresh air to breathe for our baby and a decent sized garden to play in(we lived in Hong Kong on the 52nd floor of a 1200sq ft apartment) plus the opportunity to show my wife around Europes cities and mountains and coastlines would offset the yob culture, high taxes and dismal weather. What surprised me was how hard it was after being away a few years.... you drop off all censuses and credit checking systems and you have to re establish that you are ordinarily resident in the UK even when you are British citizen!!!
In any event it is easy to be critical of the UK having lived in places like Singapore and Hong Kong where basically public services work and are efficient but the real issue in the UK for me is the lack of parental responsibility combined with a nanny state where even competitive sport at school is bad because poor Johnny might not be a winner and will emotionally scarred for life!!!!
