MEPs should be "more constructive" and invite Donald Trump to the EU Parliament to debate the USA president, Nigel Farage declared on Wednesday (1 February).
But as Farage was in full flow, Labour MP Seb Dance switched seats to sit right behind him.
Under the strict controls brought in last Friday, refugees and citizens from seven mainly Muslim countries are temporarily barred from entering the USA for 120 and 90 days respectively. The process here doesn't allow us to challenge what he's saying, ' he told Buzzfeed News.
Mr Dance said on Thursday he had "no regrets" for holding up the handwritten sign while Nigel Farage was speaking in the EU Parliament chamber.
Some saw the amusing side of Dance's sign.
He said: "It seems to me with all the anti-Trump rhetoric that is coming from everywhere, actually what we are hearing is the true nature of the European project which is genuine anti-Americanism".
Later UKIP MEP Bill Etheridge filed an official complaint against Dance to the European Parliament.
It's also emerged that Nigel Farage's wife could be caught up in the dodgy payments as she was paid as an MEP assistant while she also managed her husband's office for UKIP.
He added: "If the British Labour Party want to start making signs to display while people are talking I've got a few for them let's start with sell out".
