A member of the British entertainment industry's Fox family, he graduated from the Royal Academy of Dramatic Art and debuted in the film The Hole (2001).

[8] He was expelled a few weeks before taking his A-Level exams, and was unable to obtain a place at any university due to a report about him from Harrow.

[9] After working as a gardener[9] and in an office,[8] he decided to follow his family into acting, and successfully auditioned for the Royal Academy of Dramatic Art (RADA).

In addition, in that year Fox was seen on ITV as Cecil Vyse in Andrew Davies's adaptation of A Room with a View based on E.M. Forster's 1908 novel.

[18] In April 2007, Fox received a police caution after he was arrested for assault when he punched a photographer outside the Garrick Theatre in London where he was performing in Treats.

[26] In 2018, Fox joined the cast of the ITV series Victoria, playing Lord Palmerston, for its third season, which first aired on PBS in January 2019.

[27] In November 2020, Fox was dropped by his talent agency Artists Rights Group after stating on Question Time that an audience member's description of him as a "white privileged male" was "racist".

[31][32] In September 2023, Fox was suspended by GB News after saying of female journalist Ava Evans: "Show me a single self-respecting man that would like to climb into bed with that woman ever."

[43] Appearing as a panellist on the BBC's political debate programme Question Time in January 2020, Fox said that Meghan Markle was not a victim of racism and described an audience member who called him a "white privileged male" as racist.

"[45] He followed by apologising on Twitter to "fellow humans who are Sikhs" and wrote, "I am as moved by the sacrifices your relatives made as I am by the loss of all those who die in war, whatever creed or colour.

"[46] In August 2021, Fox posted a tweet stating "get kneeling, fuckers" about the recent arrest of black footballer Benjamin Mendy on charges of rape and sexual assault.

[50][51][52] In September 2020, Fox attracted funding for a new political party, provisionally called Reclaim,[53][54] and dubbed "UKIP for culture".

[62] In March 2021, Fox announced he would stand in the London mayoral election, in order to "fight against extreme political correctness" and pledging to "end the Met's obsession with diversity and inclusivity.

[72][73] In October 2020, Fox announced he would boycott the supermarket Sainsbury's because they "support racial segregation and discrimination", making reference to the store establishing "safe spaces" for black employees, while asking others to do the same.

[74] Feeling he was "falsely smeared as a racist", Fox replied to a number of tweets reacting to that announcement by calling their authors paedophiles.

Two of those people, RuPaul's Drag Race UK contestant Crystal (Colin Seymour) and Simon Blake, deputy chair of the LGBT rights charity Stonewall, both gay men, later announced they would sue Fox for defamation.

[75] In April 2021, Crystal and Blake lodged a claim for defamation in the High Court and were joined in the legal action by actress Nicola Thorp, whom Fox also called a paedophile.

[77] In December 2021, judge Barbara Fontaine urged the protagonists to reach a compromise; Fox's lawyers had estimated his legal costs would be between £360,000 and £500,000 for a full trial.

[82] The trial progressed at the High Court to decisions on preliminary issues such as the "natural and ordinary" meanings of the tweets, which included that they were a factual claim that "Ms Thorp was a paedophile".

The judge summarised that "Mr Fox did not attempt to show these allegations were true, and he was not able to bring himself on the facts within the terms of any other defence recognised in law".

Doll later posted on 2 August that he had filed a defamation complaint against Fox and other Twitter users through lawyer Anne-Sophie Laguens and NGO Stop Homophobie.

He was reported as having said on the previous day in an interview on Rumble that he declared support for a ULEZ vigilante group, saying: "I encourage them to tear down every single camera there is and I will be joining them [...] I am pretty close with several and I will be out there with my angle grinder.

"[92][93] On 31 January 2024, a hearing was held at the High Court whereby Fox is taking legal action against a man who called him a "racist" on social media.

Ben Gallop, representing Fox, told the court that Yassin had made "seriously defamatory allegations of racism against my client that are bare comments".

Judge Mrs Justice Collins Rice ruled that a hearing should take place to decide whether the posts were statements of fact or opinion, and what should be included in any future trial.

[105][106][107][108][109] In 2024, Piper commented on the divorce in British Vogue, where she expressed the desire for her children to have privacy and anonymity, and the difficulty of this given Fox's public profile.

[115] In an October 2012 Independent interview, Fox described himself as a "vaguely lapsed Christian" who occasionally prays and thinks "the world is a better place for people who believe in God" despite not having "squared that circle" himself.
