The SNP wants to separate Scotland from the rest of the U.K. while the UKIP wants the UK to leave the European Union. Forsyth writes:
Both of these parties are nationalist — but at opposite ends of the political spectrum. The SNP is essentially a party of the left, part of its argument for independence is that a sovereign Scotland would be a more socially democratic country.
Ukip, by contrast, is of the right. Its soul is stirred by the prospect of flat taxes, a strong national defence and a tough immigration policy. The SNP’s dream of an independent Scotland with free childcare, no nuclear submarines and increased immigration is Ukip’s idea of hell.
