Political views
According to The Guardian in 2024, Valance had "rapidly risen to become radical-right royalty". In February that year, she attended the launch of the new British conservative movement Popular Conservatism, led by former UK Prime Minister Liz Truss. In a series of clips posted on X (formerly known as Twitter), Valance was interviewed by Christopher Hope of GB News, and was asked about her views on various issues. Her view on "the climate crisis or lack of" was that "cleaner, cheaper energy is what we need". Asked about her political views, she said, "I would say that everyone starts off as a leftie and then wakes up at some point after making money, working, trying to run a business, trying to buy a home then realises what crap ideas they all are, and then you go to the right." Valance said her top political priority was Britain leaving the European Convention on Human Rights and the establishment of a British bill of rights, adding that "the trickle-down effect would be a huge step in the right direction".
A close personal friend of Nigel Farage, Valance said she persuaded him to stand for Parliament in the 2024 general election. In a 2024 interview she stated she was a member of Reform UK and would be voting for them in the general election. She said, "I support anybody that sticks to what they believe in and isn't a turncoat, and doesn't do a million flip-flops and U-turns." She helped the party raise £1.5 million within days of Farage's return as leader, and has donated approximately £100,000 herself. In December 2024 it was announced that Valance's husband would become treasurer of Reform UK.
Having previously stayed at Donald Trump's Mar-a-Lago resort, in 2024 Valance became the "UK poster girl" for Trump's US presidential campaign, and co-hosted a large fundraiser in London on 11 June.
In September 2025, Valance attended the Unite the Kingdom protest, and said of the British far-right activist Tommy Robinson: "I'm very proud and pleased for Tommy, this is his redemption."
