MPs debated Donald Trump's state visit to the United Kingdom, after a petition against his visit reached 1.85 million signatures and a petition in favour of his invitation gained 311,000 signatures.
Trump opponents plan to demonstrate outside parliament in London as legislators hold a debate Monday.
A petition before the House of Commons today seeks to put a moratorium on a Trump state visit throughout his term, because having one would "cause embarrassment to Her Majesty the Queen".
Mr Flynn highlighted the fact that Mr Trump is only the third U.S. president to be given the honour of a state visit and said he was invited too soon in his already highly controversial presidency.
The debate in Parliament on Trump's proposed visit began when Speaker John Bercow voiced his opposition to the idea of Trump addressing Parliament, a break from the historic neutrality of Bercow's position.
MP Paul Flynn said only two US presidents have been granted a state visit since 1952, but within seven days of Trump becoming president he had been invited to a state visit.
The heated exchange saw Tory lawmakers attempting to fend off ferocious attacks against Trump by left-wing MPs from Labour Party, Green Party and Scottish National Party (SNP). "It would be terribly wrong because it would appear that British Parliament, the British nation, the British sovereign is approving of the acts of Donald J. Trump".
Labour MP Paul Flynn led the discussion, arguing that while he respected the U.S. presidency he believed "the intellectual capacity of the incumbent is protozoan" - a single-celled organism.
He is not the first US president to be accorded a full state visit to Britain, traditionally including a horse-drawn-carriage ride with the queen and a formal banquet at Buckingham Palace.
Former USA Gymnastics Doctor Charged With Sexual Assault
Larry Nassar listens to testimony of a witness during a preliminary hearing Friday, Feb. 17, 2017, in Lansing, Mich . Schuette had previously charged Nassar with repeatedly molesting a family friend starting when she was 6 years old.
Responding to concerns about Mr Trump's "grab them by the p--" gaffe, Sir Edward Leigh claimed: "Which one of us has not made some ridiculous sexual comment?"
"It's extraordinary that Trump, from the cavernous depths of his scientific ignorance, is prepared to challenge the conclusions of 97 percent of the world's experts on this matter", agreed Labour Party MP Paul Flynn, who later described Trump as a "petulant child" for his behavior.
The second video includes the full remarks of Conservative MP Nigel Evans, who says that even though he doesn't condone all of Trump's actions and statements, critics need to "get over it" and respect America's electoral outcome.
Earlier this month, U.K. Prime Minister Theresa May visited the White House to meet and and talk shop with President Trump.
No US President has received a state visit in his first year in office.
Evans, who said he didn't "like some of the things (Trump) has said in the past", went on to argue he had seen "no evidence of (Trump) being racist". "I am ashamed that it has come to this".
But David Lammy opposed the state visit.
But he added "there's room for pragmatism and visits can happen more quickly". A lot of them thought that the U.S. president is racist and sexist, and therefore should not be allowed to visit their country.
The lawmakers jointly debated a rival petition calling on the British government to stand by the invitation.
