Your link is a typical far-left article, but taking a passage from it, not a selected piece altered by you, I would think that the majority of the British public would agree with most of this, if one first ignores the far-left introduction.
Note the obligatory name calling, nationalist, xenophobic,
Eurosceptic, similar to radical right parties on the continent,
/// UKIP:
/// Though formed to oppose European integration, since 2001
the UK Independence Party (UKIP) has developed a suite
of radical right-wing policies. By 2010, and like the BNP,
UKIP was offering a combination of nationalist, xenophobic,
Eurosceptic and populist policies. Similar to radical right parties
on the continent, ///
Now we will address what they call 'populist policies'
/// UKIP demanded that Britain end mass and
‘uncontrolled immigration’, though unlike the BNP it proposed
a five-year freeze. In addition, there were pledges to regain
border control, expel illegal immigrants, remove benefits for
remaining immigrants, repeal the Human Rights Act and ‘end
the active promotion of the doctrine of multiculturalism by local
and national government and all publicly funded bodies’.
UKIP
also played on other radical right themes, calling for an end to
political correctness, urging citizens to recognise ‘the numerous
threats to British identity and culture’, advocating a ban on the
burqa in public buildings, and inviting Geert Wilders to show his
anti-Islam documentary Fitna in the House of Lords. ///
Yes I think it is fair to describe these as 'populist policies'.
