Nigel Farage’s Reform UK won its first council in London at the May local elections.

A new poll now shows his party’s London mayoral contender Laila Cunningham could get to the run-off against Labour in the race for City Hall in 2028.

The Savanta survey for The Mile End Institute, Queen Mary University of London, put Reform on 20%, behind Labour on 33% but ahead of the Tories on 18%, the Greens 14% and Liberal Democrats 10%.

So, who are the Londoners backing Mr Farage’s party?

More male than female voters are supporting Reform.

The party is getting 24% of the vote of men, according to the poll, and 17% for women in voting intention for the next Mayor of London election.

The perception is also that older people lean Reform.

But the survey showed by far the biggest group of voters in London turning to this party is 45 to 54-year-olds.

Reform picked up 38% of this age group in voting intentions for London mayor, compared to 22% for those aged 55 and over.

Dr Eoghan Kelly, a postdoctoral researcher in British Politics at Queen Mary University of London, said: “Reform voters are older than average, but the party hasn't broken through amongst the oldest age groups who are sticking with the Conservatives.

“It is predominantly people in their 40s, 50s and 60s who are opting for Reform.

They are mostly white, male, less well off, and less well educated.

“There isn't a big Inner/Outer split, but Reform are bigger in the eastern half of London especially as you approach Kent or Essex.”

Reform is also getting the backing of some young Londoners, aged 18 to 24.

Thirteen per cent of this age group would vote for Ms Cunningham, the survey suggested, as would 11% of Londoners aged 24 to 35, and 18% of those 35 to 44.

The age group results, and some other categories, need to be treated with some caution given the small sample sizes in a poll of 1,036 adults.

But the findings on Inner London, long a Labour stronghold, and Outer London, where Reform did best at the local elections winning control of Havering, should be more robust given there are just two categories rather than four or five.

The poll showed Reform getting 21% of the mayoral vote in Inner London and 20% in outer boroughs.

A more detailed geographical breakdown put it on 23% of the vote in eastern boroughs, 21 in the west, 19% in the south, 18% in the north and 16% in central areas.

Reform is picking up 30% of the vote among white people, and 8% from ethnic minority communities.

One in five single people (19%) would vote for Mr Farage’s party in the mayoral contest, 17% of those who are married or in couples, and 44% of individuals who are separated, divorced or widowed.

Eighteen per cent of lesbian, gay or bisexual Londoners would vote for Ms Cunningham, according to the poll, as would 21% of heterosexual/straight people.

Nearly a quarter of Londoners (23%) without children say they would vote Reform, compared to 18% with children.

Reform gets more than double the support from people who have not been to university, 33%, compared to 14% of graduates.

A third of London voters (32%) living in social or council housing back the party, more than the 22% for Labour, as would 18% of tenants renting privately, 19% of homeowners with or without a mortgage, and 16% of those living at home with their parents.

One in four Londoners with household income below £30,000 favour Reform, compared to 18% for the £30,000 to £49,999 category, and 20% for those on £50,000 or more.
