Nigel Farage, leader of the British anti-EU party UKip, will visit the Netherlands in April, two days before the Dutch referendum on the EU’s treaty of association with Ukraine.

Farage has been invited by right-wing party VNL and the GeenPeil organisation which campaigned for the referendum, to drum up interest in the Dutch vote.

‘If you win in your referendum, my goodness me, that will help in Britain too,’ Farage says in a video message advertising his appearance. The British referendum takes place on June 23.

Although the Dutch referendum is technically about the treaty with Ukraine, it is widely being seen as a test of public opinion about the EU in general.
