> The Channel Islands, Gibraltar and the Isle Of Man I believe are constantly being used for the purpose of tax evasion, money laundering etc... that’s what frightens me about Brexit - I think the hard Brexiteers actually want to make this easier, not harder.

It's the one single thing that makes me most pro-EU. I don't see how we can fight tax evasion on a country-by-country level. But a economic and geographical bloc as big as the EU has enough clout to have real enforcement power.
