The interview came after Donald Trump's eyebrow-raising victory in the November 8 presidential elections in the United States, in which he managed to get the better of the Democratic candidate Hillary Clinton.
When asked about how the US political establishment reacted to Trump's triumph, Arterton said that he thinks "people are traumatized because this is a very unexpected presidential race, given that all of the prognostications indicated that Clinton would win."
"This was quite a substantial victory for Donald Trump; it sets Washington on edge because nobody really knows what they get," Arterton said.
In this vein, he recalled that "some years ago, Trump had some polices" that were in line the Democratic Party and out of line with the Republicans. Then he ran as a Republican and over the course of his campaign, became increasingly Republican.
"So people are holding their breath to see which Donald Trump is actually going to be president," he said referring to the "transition process" Trump will have to deal with after meeting outgoing US President Barack Obama.
According to Arterton,"Trump will have a very tough time reaching out to those people who supported Hillary Clinton."
Touching on Trump's address to the nation, Arterton touted it as a "good speech" in which he said Trump, in particular, "reassured foreign leaders and foreign citizens that the United States will be fairer in dealing with other countries while always putting US interests first."
"I don't think there will be significant changes in the immediate future, as far as Washington's ties with the EU and NATO are concerned," Arterton said, adding that "Trump will not go so far as to dismantle NATO, pull out of the alliance or significantly weaken NATO."
The governments of Britain, China, Germany, Israel, Japan, Russia and Turkey congratulated Trump and said they would cooperate with him.
Earlier this week, Trump addressed the nation in the first speech following the presidential election. Speaking at his headquarters in New York on Wednesday morning, Donald Trump thanked his supporters, pledging to renew the American dream so that every American will have the opportunity to realize his potential.
