“Almost every constituency we targeted, we won”: The inside story of Labour’s ground game

An ambitious strategy from Momentum swung marginal seats to Labour – and united the faction-riven party.

By Anoosh Chakelian

From California to Canterbury, a handful of young activists began messaging each other the minute Theresa May called a snap election on 18 April. They were making plans that would, seven weeks later, help deprive the government of its majority – and bring the Labour party closer to government.

“When the snap election was called, I came the weekend after,” recalls Erika Uyterhoeven, a 30-year-old Bostonian who was employed by the Bernie Sanders campaign during the US election.

She was its National Out-of-State Organiser, which meant the difficult job of rallying activists to go and canvass in places that were often a five-hour drive away from where they lived – in marginal states rather than their own areas.

Uyterhoeven had helped out with Jeremy Corbyn’s second leadership campaign, advising Momentum – the membership movement that grew out of Corbyn’s network of supporters in 2015 – on how to train its volunteers in canvassing. The group got hold of her again, after May’s election announcement, and asked her to bring some colleagues. The training was going to be on a much bigger scale this time round.

“Hey, does anybody want to come? They’re doing this big training programme, they want people from the Sanders campaign to come and do it,” is the message received by her friend Jeremy Parkin, a 27-year-old from California who worked on the New Hampshire, Massachusetts, Maine, Utah and California primaries, and then for community organisers on behalf of Hillary Clinton’s campaign. They had worked together in New Hampshire.

“Erica had been helping out with Momentum for a while, so she reached out to some people from the Bernie campaign,” Parkin adds. “We’d heard about Corbyn in the States and it was really cool – he was this guy who was doing similar to what Bernie was doing over there. I thought it was a great opportunity to come and help Corbyn out.”

Twenty days later, he was in Momentum’s shabby office in Euston, central London. It was here that he, Uyterhoeven and two other former Sanders staffers planned a programme that would train over 3,000 Momentum and Labour members in canvassing techniques – and develop digital tools to mobilise activists across the country. They worked as volunteers.

“Almost every constituency Momentum targeted, we won.”

The weekend following the election, I meet Parkin in the foyer of the building, owned by the TSSA union. It is a concrete block that looms over the rather appropriately named Melton Road (“melt” is an insult used online by some Corbyn supporters).

Parkin is a lanky figure in baggy jeans, suede Pumas and a grey t-shirt, bouncing over with remarkable energy for someone who has been working non-stop the past month. He introduces himself in his broad Californian accent. He tells me they were doing three or four training sessions a week up until polling day: one in London and then all over the rest of the country per week.

“I went up north a lot, did a few trainings up in the Midlands, and then in Manchester and Liverpool too,” he says, as we sit down, shaded from the sunshine outside.

In these sessions – where sometimes 300 people would turn up; the smallest had 20 attendees – volunteers were taught how to do “persuasion canvassing”. This is a technique that uses a “response cycle” – empathising with a voter’s concerns on the doorstep, isolating the main thing they are worried about, and then giving relevant information about your candidate to address those concerns.

It sounds quite basic, but lots of first-time doorknockers would overload voters with non-specific information about Labour’s manifesto, or end up in a confrontation with people they didn’t agree with, for example on Corbyn’s leadership.

“It’s really overwhelming and kind of in your face, right?” says Parkin. “So one of the things I worked on at first was acknowledging concerns and building empathy. That’s a big thing of what I do.”

This is a shift from Labour’s time-honoured Voter ID method, which Parkin demonstrates sarcastically: “Knock knock. Hi! Are you voting Labour? Yes. Great, thank you! No. Great, thank you! Maybe. Great, thank you! Bye!”

Once trained, Momentum’s volunteers were sent to marginal seats no one – the Labour party included – believed were winnable. Groups of hundreds went to Croydon Central, Kensington, Canterbury, Battersea, Sheffield Hallam, Brighton Kemptown, Leeds North West, Crewe & Nantwich, Lancaster & Fleetwood, Hampstead & Kilburn, Derby North, City of Chester, and Ealing Central & Acton.

Momentum held about 50 campaign weekends in marginal seats.

“In some places we were the only ones doing a lot of it”

This was enhanced by the My Nearest Marginal online tool, the growing impact of which the New Statesman wrote about before the election. This provided a car pool service for participants to travel easily and cheaply to target marginal seats. You just type in your postcode, and the map shows where it’s most useful for you to go.

By polling day, 100,000 people had used the site – that’s nearly a fifth of the whole of Labour’s membership, and four times that of Momentum.

“Almost every constituency Momentum targeted, we won,” says Parkin. Compare this to Tory support in swing seats – of the 43 marginal constituencies May visited during the election campaign, only five went Conservative.


There was suspicion at first from Corbynsceptic MPs in marginal seats. Local Labour parties have often clashed with their Momentum counterparts, unable to reconcile their opposing opinions on the Labour leader.

Lack of Momentum presence was felt in some areas. “They’d rather stick to slagging the MP off on Facebook,” one Labour aide in a marginal northern seat lamented a few weeks before the election. “There’s all these new members, hundreds of new members, and none of them are doing anything, literally refusing to come out.”

At the start of the campaign, accusations flew around that My Nearest Marginal was directing activists away from helping MPs critical of Corbyn, such as Bermondsey & Southwark’s Neil Coyle. This was soon resolved, put down to a slow updating of information.

Some in Labour HQ were privately accusing Momentum of scraping data about campaign events from the main party site. Frustrated Momentum figures, in turn, were claiming that local parties in Sheffield and Battersea were directing activists elsewhere. “I think our campaigning made a difference in those kind of places – simply because we were the only ones doing a lot of it,” says one Momentum insider.

But by all accounts, relationships improved between Momentum and the rest of the party when the group proved it was pounding the pavements. “We’ve been able to actually see each other face-to-face, rather than briefing through the press,” a Momentum source tells me. “I do think this election’s really good for party unity. Not just in the sense that we did incredibly well, but also just that we’ve had the opportunity to work together, very closely.”

New MPs representing marginal seats are grateful. Croydon Central’s Labour candidate Sarah Jones, who didn’t vote for Corbyn and is aligned with Progress, was impressed with the “absolutely tonnes” of Momentum activists who had turned out for her when my colleague Julia joined her on the campaign trail.

“It was a completely different kind of campaign”

After being elected, she told the Guardian: “So many of the first-timers and Momentum people would come back, that was the amazing thing – and after two sessions they were the experienced ones, leading the new ones. It was a completely different kind of campaign.”

Sheffield Hallam’s new MP, Jared O’Mara, who ousted Nick Clegg, said in a statement: “The contribution of Momentum members in South Yorkshire and beyond was exemplary. It was a blessing to have them on board campaigning to get me elected.”

It was in O’Mara’s constituency where 69.2 per cent of 18-25 year olds with a Facebook profile watched at least one Momentum video online. The group calculates that nearly 30 per cent of all UK Facebook users viewed one over the campaign, with figures particularly high in marginal seats – for example, 35 per cent of Facebook users in Battersea watched a Momentum video.

The organisation also used peer-to-peer texting, which simply means sending out geographically targeted texts from Momentum telling members about local events or cavasses coming up – messages that can then be forwarded to friends. The open rate of texts is much higher than with emails, which are easily ignored.

On election day, 400,000 people received a Whatsapp “cascade” message sent out by Momentum to rally people to go out and vote.

Following another Sanders campaign method, Momentum also made a phone bank app that could be used by supporters from home. So from your sofa, you could call vast numbers of people to canvass – with the follow-up question asking them to pledge part of their day on 8 June to get out the vote.

“We’ve been asking that since the beginning of the election,” says Uyterhoeven. “We asked all our activists and supporters to pledge to take the day off work to knock on doors for Labour.”

This resulted in 10,000 people knocking on more than 1.2 million doors on election day.

Not bad, for a group of 24,000 members with a handful of paid staff and £2,000 to spend on Facebook advertising. With the full weight of a unified Labour party of nearly 700,000 members behind it, Momentum could help win constituencies vital for victory next time round.

“I wouldn’t mind coming back here and working another election,” grins Parkin. “There’s probably going to be another soon.”
