Dog whistle politics.
It shows how the political landscape in UK (and probably other countries) has deteriorated since the advent of social media.
Dog whistle politics has always been available via the established media. But now the opportunities to bang on about an issue, however minor, and to add colour, and raise awareness, whether warranted or not, are easily available via social media.
The original story was raised by Lord Ashcroft, an ex-Tory Dep' Chairman.
Lord Ashcroft is a resident of Belize, where ha has not paid tax for 30 years, by his own admission. As a resident of Belize he was mostly exempt from tax in UK.
During his post with the Tory party, he said he would register for tax in UK. He never did.
Look, there's a squirrel.
