The ignorance about these investment is amazing , this was NOT a private family overseas trust , it was not even a trust at all .It was an investment in an open ended investment company ( similar to a unit trust ) .It was a company registered in Panama , and domiciled in Ireland for reasons other than tax .It was fully regulated under the uk investment regulations.
Anyone can buy units in an OEIC and most are held via roverseas registered companies .Millions of people in this country have units in similar vehicles , if you have a managed stocks and shares ISA or a pension fund it will probably hold units in an OeIC.This fund was open to any investor , albeit at the riskier end of the scale , it's about as common investment as you can get after a bank account.
There is NO tax saving for the individual , this was an income fund so all the income was paid out every year and is put on the recipients tax return and income tax paid .On disposal the gain is declared and taxable in the same way .
DC probably held this as part of a wider portfolio , as is common with people holding public office he probably instructed the whole portfolio to be sold when he took office , he probably didn't routinely look at the individual holdings and almost certainly would not have been aware that it was registered in Panama.Has anyone here who holds shares in unit trusts or in an ISA checked to see where the underlying company is registered .If you are really concerned you should look because it often is not the UK .
This is a complete storm in a teacup , made up by the media and fuelled by the politics of envy .Very few intelligent people in politics are critiquing him because they probably have these investments too .
