I was greatly disappointed when I learned of United Kingdom's immigration law changes that went into effect December 2012.
I have been coming to the UK consistently in the past decade so this change is disheartening since it affects my current entry standing.
I apologise to my fans that were inconvenienced, however, please know I am currently working diligently with the proper authorities to regain access next year for my UK tour...
I have a great deal of respect for the laws of the United Kingdom and will continue taking the proper steps for re-entry.
Former heavyweight champion boxer Mike Tyson has said he was "greatly disappointed" when he learned he could not enter the UK and would "continue taking the proper steps for re-entry".
The ban on former boxer Mike Tyson from entering the UK is "mandatory" because of the length of his jail sentence for rape.
Under tougher immigration rules introduced in December 2012, there is "a mandatory refusal where a person has been convicted of an offence and sentenced to at least four years' imprisonment, at any point in the past."
Although Tyson only served three years in prison for the crime, he was sentenced to six years.
A campaign group that tackles disbelief around domestic and sexual violence has praised laws barring former boxer Mike Tyson from visiting the UK.
Ending Victimisation and Blame said the ban "sends a message" about the consequences of criminal actions.
– Spokesperson for Ending Victimisation and Blame
We are delighted that Mike Tyson is not being allowed into the UK due to his previous convictions, one of which was for rape.
We believe that this sends a message that his criminal actions have long-term consequences - sadly, the consequences for his victim seem to have been forgotten by both Mike Tyson and his supporters.
Former world heavyweight boxing champion and convicted rapist Mike Tyson has discovered he is banned from entering the UK.
The 47-year-old has cancelled a string of appearances in London as part of a promotional tour for his new book after finding out he was banned from Britain.
His publishers said recent changes to UK immigration rules, including any person sentenced to more than four years in prison being banned from Britain, meant he was unable to travel.
Tweets posted on Tyson's official Twitter account as recently as Friday suggest the boxer was unaware he would be hit by the changes. He wrote: "So, UK fans, who is brave enough to get in the ring and ask me a question?"
Tyson will now promote his autobiography Undisputed Truth in Paris.
Ukip councillor Victoria Ayling has defended herself after a video of her emerged of her saying she would like to "send the lot back" when talking about her political position on immigration and multiculturalism.
Mrs Ayling said her comments within the video, made by her ex-husband, had been taken out of context, and she was referring to illegal immigrants.
Shadow immigration minister David Hanson called for an apology after comments made by Ukip councillor Victoria Ayling.
"This type of offensive language should have no place in modern Britain," he said.
"British people do not deserve to be 'sent back home' because this is their home.
"It has taken us years to defeat the ideology and language of the NF [National Front] and the views of the BNP [British National Party] and they should not be resurrected by someone calling themselves a serious politician.
"She needs to apologise and repudiate the use of this type of language and thinking."
Other remarks made by Ukip councillor Victoria Ayling in the Daily Mail video include:
...send them back.
[Rob Ayling] It's a bit National Front isn't it?
[Victoria Ayling] It's right though. But anyway...
Multiculturalism does not work - Britishness does.
[Away from camera] Multiculturalism is dead, I'm allowed to say that but maybe 'Britishness' is waving the National Front flag a bit.
I just want to send the lot back, but I can't say that.
[Rob Ayling] We'll nip that out in case...
[Victoria Ayling] Bribery, blackmail! We need the blackmail music, don't we!
Victoria Ayling told the BBC that her "send the lot back" comments were made in reference to illegal immigrants and that the Mail story was based only on "snippets" of the political video she made with her husband in 2008.
Ukip leader Nigel Farage told the Daily Mail that Victoria Ayling’s comments were "slightly odd", but added:
I have met her two or three times and I have discussed policy at length before accepting her into the party.
I had no reason to believe she held views that were extreme or inconsistent with ours.
While this comment looks odd and unpleasant there may be a context here that is slightly different to the way it appears.
