Donald Trump and the First Lady Melania were welcomed by the Queen on the first day of their three-day visit to the UK amidst the threat of mass protests.
Despite the protests about his visit, Sarah Elliott a Christian and chair of Republicans Overseas UK told Premier plenty of good can come out of it.
"Free trading arrangements are being discussed and the foundations for that.
"Also I think it's very important that both of our countries continue to work together - especially on security and intelligence sharing."
Mr Trump sparked controversy minutes before he landed at London's Stansted Airport when he called the London Mayor a "stone cold loser" on Twitter.
It followed Sadiq Khan's comments that the UK should not "roll out the red carpet" for Mr Trump.
....Kahn reminds me very much of our very dumb and incompetent Mayor of NYC, de Blasio, who has also done a terrible job - only half his height. In any event, I look forward to being a great friend to the United Kingdom, and am looking very much forward to my visit. Landing now!— Donald J. Trump (@realDonaldTrump) 3 June 2019
Simon Barrow from Christian think tank Ekklesia told Premier's News Hour Mr Trump's language was unacceptable.
He explained: "It doesn't seem very presidential behaviour and I'm tempted to ask, 'who would Jesus call a loser?' that wasn't the language of Jesus.
"Jesus blessed the poor, he welcomed the stranger, he called on his followers to put away the sword, he honoured God's creation and he blessed those who cursed him.
"I will be joining protestors and I'll be doing that as an act of Christian witness against many of the things that President Trump stands for, which I think are anti-gospel and being promoted in the name of Christianity."
Mr Khan hit back with his office describing the US President's comments as "childish insults."
Mr Trump had a private lunch with the Queen at Buckingham Palace before going to Westminster Abbey. He will attend a state banquet in the evening, which several leading politicians are boycotting.
