Morris Katz, a senior political strategist who worked on New York City Mayor Zohran Mamdani’s 2025 campaign, traveled to the United Kingdom in February for meetings with Labour and Green Party figures about campaign tactics and messaging, according to POLITICO.
Katz told POLITICO that he viewed the outreach as part of a broader transnational political struggle. “The fight against the aligned interests of the oligarchy and the far right is an international one, and I’ll try to be helpful wherever I can,” he said.
POLITICO reported that Katz met with Labour MPs Rosie Wrighting and Gordon McKee and with Rowenna Davis, Labour’s selected candidate for executive mayor of Croydon in south London. The report said the discussions included digital strategy and messaging, including the use of short-form social media content.
Katz’s trip followed a late-February UK parliamentary by-election in the Manchester-area seat of Gorton and Denton, where the Green Party won and Labour finished behind it. The winner, Hannah Spencer—a local councillor who has worked as a plumber—ran on cost-of-living themes. In a Guardian article published after the result, Spencer wrote: “We ran a hopeful campaign backed by thousands of volunteers and activists. We defeated the parties of billionaire donors.”
Mamdani rose to national prominence after defeating former New York Gov. Andrew Cuomo in the June 2025 Democratic mayoral primary and then winning the November 2025 general election for New York City mayor, according to election results published by the New York City Board of Elections and reporting by The Associated Press.
POLITICO reported that Katz’s UK meetings were unpaid and that he expected to continue some conversations remotely. Spokespeople for both Labour and the Green Party did not comment to POLITICO.
The report also noted that American political operatives have previously advised UK politicians, including around former Labour leader Jeremy Corbyn’s campaigns.
