Thanks to an online petition that has garnered more than 325,000 signatures, Britain's parliament has taken up debate on Jan. 18, 2016, over whether or not to support a ban on Donald Trump for hateful and offensive comments. The famous and notorious who the U.K. has declared unfit to enter the country include Martha Stewart, Hamas MP Yunis Al-Astal, a conservative American talk show host and members of the Westboro Baptist Church. Since 2005, Britain's Home Office has had wider latitude to ban those it deems to be promoting hatred, terrorism or serious criminal activity.
In 2004, celebrity homemaker Martha Stewart was convicted of lying about selling stock that plunged in price soon after her trade, related to the ImClone Systems insider trading scandal and sentenced to jail time.
She served five months in prison followed by five months of home detention.
When Stewart was banned, the U.K. Border and Immigration Agency released a statement, according to The Independent newspaper, saying the government "continues to oppose" entry for those who have been found guilty of "serious criminal offenses abroad."
Pastor Terry Jones of the Dover World Outreach Center, who ignited a firestorm across the world with his ultimately scuttled plans to burn a Quran on Sept. 11, followed through with a the burning of a Muslim holy book after staging a mock trial finding the Quran guilty of crimes against humanity.
Jones can be seen in this photo acting as the judge conducting the mock trial of the Quran, at the Gainesville, Florida church, March 20, 2011.
Former NSA contractor Edward Snowden flew to Moscow in 2013, after revealing previously secret information about the National Security Agency, Britain's GCHQ and other intelligence agency programs to eavesdrop on a vast scale.
He faces U.S. charges that could land him in prison for up to 30 years if he ever returns. Life in Moscow keeps him safe from prosecution.
Former heavyweight boxing champion Mike Tyson is banned from Britain because of his rape conviction. Tyson learned he was banned from entering Britain in 2013, when he was planning to fly there to promote his autobiography, "Undisputed Truth."
The boxer was convicted in 1992 for rape and sentenced to six years in prison, of which he served three. Past convictions included those for cocaine possession, assault and DUI.
Britain's immigration rules tightened up in 2013 so that anyone who has served more than four years in prison is not allowed to enter the country.
Controversial Nation of Islam leader Louis Farrakhan was banned from Britain in 1986 because the British government said he expressed views that were racist and anti-Semitic. His lawyers unsuccessfully challenged the ban in 2001 in the High Court in the U.K., saying he had "moved on" and was regarded in America as a significant spokesperson for the black community. A court of appeals, in ruling to keep the ban, stated that it took into account tensions in the Middle East and the risk of public disorder that a visit by the Chicago-based activist might bring.
In this photo, Farrakhan speaks at a press conference near United Nations headquarters June 15, 2011, in New York City.
Radio talk show host Michael Savage
In 2009, Britain announced that conservative radio talk show host Michael Savage (born Michael Weiner) was on a list of 16 people banned from the U.K. because of concerns that their views could provoke violence. Then-British Home Secretary Jacqui Smith was quoted as saying it was "important that people understand the sorts of values and sorts of standards that we have here, the fact that it's a privilege to come and the sort of things that mean you won't be welcome in this country." The ban was reaffirmed in 2011 despite lawyers' attempt to have it lifted.
Savage, who hosted the nationally syndicated talk show "The Savage Nation" is seen here in Tiburon, Calif. on Dec. 3, 2007. While he calls himself a conservative nationalist, his critics say he fosters extremism. The BBC identified his views on immigration, Islam, rape and autism as causing serious offense.
Dog the Bounty Hunter Duane Chapman
Duane Chapman, who made his mark with his hit reality TV show "Dog the Bounty Hunter," had to contend with the repercussions of his own criminal history when he was banned from the U.K. in 2012. He was denied entry because of the 1976 murder of Jerry Olivery in Pampa, Texas.
Though it was Chapman's friends who killed Oliver during a drug buy while Chapman remained in car outside the house, he was nevertheless convicted of first-degree murder. Chapman was sentenced to five years, but served one-and-half years before his release.
Here, Chapman poses with a fan outside a press conference where New York Gov. Andrew Cuomo, was speaking to the media about the capture of convicted murderer David Sweat on June 28, 2015 in Malone, New York.
Both Shirley Phelps-Roper and her father Fred Phelps, leader of the Westboro Baptist Church, were banned from Britain in 2009 when they planned to protest a play in the U.K., "The Laramie Project," about a man killed for being gay.
In this photo, Phelps-Roper told BBC News the decision would "bring great wrath upon your heads." The church is well known for its hatred of homosexuals and its protests at funerals for soldiers in the U.S.
Phelps-Roper protests across the street from the Edward Hines Jr. VA Hospital, April 19, 2006 in Maywood, Illinois. As many states have drafted laws limiting access near funerals members of the church began to focus on veteran's hospitals as a means of getting their anti-gay message heard.
Pastor Fred Phelps, seen here preaching at the Westboro Baptist Church in Topeka, Kan. March 19, 2006, was named by Britain's Home Secretary Jacqui Smith as a "hate promoter" along with his daughter and 14 others, when a list of people barred from entering the UK was published on May 5, 2009.
A spokesman for the U.K. Border Agency was quoted by the BBC stating, "Both these individuals have engaged in unacceptable behavior by inciting hatred against a number of communities."
Phelps died in 2014.
L. Ron Hubbard
Britain's Minister of Health Kenneth Robinson described Scientology in a House of Commons speech in 1968 as a "a potential menace to the personality and well-being of those so deluded as to become its followers" as well as so objectionable that all measures should be taken to curb its growth. That led to a ban on the immigration of foreign Scientologists. L. Ron Hubbard moved Scientology's headquarters out of Britain and left the country in 1969.
The ban resulted in more than 140 people being barred from the country. The general ban was reversed in 1980 and Scientology was classified as a religion for immigration purposes in 1996. Hubbard remained banned until his death in 1986, relating to a fraud conviction in France.
Rapper Snoop Dogg was banned after a Heathrow Airport fight in 2006, when British Airways staff prevented his crew from entering the first-class lounge. The altercation resulted in Snoop getting arrested. According to The Guardian newspaper, seven police officers were injured in the melee. He was denied a travel visa the following year and wasn't allowed back in until 2010.
Snoop is no stranger to run-ins with the law, and more specifically immigration law. He has been banned from Australia because of his "string of convictions" and overstaying a previous visa. Norway, where he was busted for trying to enter the country with marijuana, banned him for two years.
Apparently the NFL isn't so keen either because Katy Perry told Elle magazine that they blocked Snoop's appearance during her Superbowl Halftime show in 2015.
Here, Snoop performs at a Super Bowl party hosted by Playboy magazine in Dallas, Texas, Feb. 4, 2011.
R&B singer Chris Brown got himself banned from the U.K. in 2010, following his conviction in the U.S. for assaulting his then-girlfriend Rihanna in 2009.
In this photo, Chris Brown and Rihanna attend the 55th Annual Grammy Awards on Feb. 10, 2013, in Los Angeles.
Britain wasn't the only country to have issues with Brown's domestic violence. The singer found himself banned from Australia in 2015, after applying for a visa ahead of December concert dates in the country, despite visits in 2011 and 2012 after his conviction. He'd been banned from Canada earlier in the year for the same reason.
Here, Brown appears in court for a probation violation hearing with his attorney Mark Geragos (R) in Los Angeles Court on May 9, 2014. He was sentenced to five years probation, a one year domestic violence program and 180 days of community service.
