Boston Mayor Wu, Glasgow Leaders Formalize Sister-City Partnership After World Cup Energy

At The Haven in Jamaica Plain, fans greeted Mayor Michelle Wu with chants “No Scotland, no party” and then “No Wu, no party” as she signed the declaration. Wu was also welcomed by an Inverness resident, Iain MacGillivray, who greeted her with a bagpipe serenade. (These details add texture to the signing scene beyond the letter-of-intent venue.)
Local businesses reported specific, quantified spikes during the World Cup stretch: Noelle Somers, chief operating officer at Hennessy’s Bar, told the Boston Globe that sales “tripled” compared with St. Patrick’s Day levels since the tournament began.
The letter of intent included explicit thematic language about what the cities plan to pursue together: both sides committed to “inclusive growth and global engagement,” intended to lay “the foundation for a meaningful and mutually beneficial partnership.”
Boston also took short-term policy action to accommodate fans: the city “passed the temporary ‘Tartan Army Bill’” allowing over 140 businesses to extend operating hours during the tournament period. Mayor Wu also wore a Scotland national team jersey during the announcement.
Glasgow leadership framed the relationship with language emphasizing substance and reciprocity: Glasgow City Council Leader Susan Aitken said the goal is to build a “partnership of real substance.” The article also reported that the deal would make Boston Glasgow’s 10th twin city.
Boston and Glasgow are officially on their way to becoming sister cities. Mayor Michelle Wu signed a letter of intent with Glasgow City Council Leader Susan Aitken on June 18 at The Haven, a Scottish tavern in Jamaica Plain. The deal caps a week in which more than 20,000 Scottish fans — known as the Tartan Army — flooded Boston for the 2026 FIFA World Cup and, by all accounts, won the city over. Boston Herald reported that Wu wore a Scotland jersey at the signing.
Wu credited the fans directly. "Boston is clearly the best host city for the World Cup right now," she said, "thanks in large part to the Tartan Army." She added the partnership would move from celebration to "concrete collaboration." The two cities plan to finalize a full agreement in April 2027, timed to Tartan Day in Boston, according to NBC Boston.
The signing scene was anything but formal. Fans inside The Haven greeted Wu with chants of "No Scotland, no party" — then quickly switched to "No Wu, no party." An Inverness resident named Iain MacGillivray serenaded her on the bagpipes as she walked in. Wu signed the declaration under the letter's stated goal of "inclusive growth and global engagement," language both sides say will guide their work ahead, according to Boston.com.
Glasgow City Council Leader Susan Aitken said she wants a "partnership of real substance." She pointed to shared priorities in climate and innovation as the foundation. The deal makes Boston Glasgow's 10th twin city, joining Havana, Marseille, and Nuremberg, Fox Sports reported.
The economic jolt was hard to miss. Noelle Somers, chief operating officer at Hennessy's Bar, told the Boston Herald that sales "tripled" compared with St. Patrick's Day — the bar's previous high-water mark — since the tournament began. The Samuel Adams Boston Taproom sold four times its normal holiday volume and ran out of beer entirely, according to the research briefing.
The Haven's owner, Jason Waddleton, ordered more than 100 kegs of Tennent's Lager just to keep up. The Tartan Army also pledged more than $20,000 to local Boston charities as a thank-you for the city's hospitality. Over 5,000 fans marched to Fenway Park for a Red Sox game on June 14, creating viral images that spread far beyond sports media.
Boston did not just welcome the fans — it changed its rules for them. City officials passed a temporary ordinance, quickly dubbed the "Tartan Army Bill," allowing 144 local businesses to extend operating hours to 2 AM. The city also created open-container zones so fans could celebrate safely on the streets, according to Boston.com.
Governor Maura Healey also got in on the goodwill, joining a viral "haggis legal" prank with Scottish podcasters. Britain's consul general in Boston attended the festivities, signaling that the week had real diplomatic weight behind the fun. The temporary measures set a model Boston may use for future large events.
The letter of intent is just the start. Municipal teams from both cities will work through 2026 on specific projects in climate resilience, innovation, education, and arts. First Minister of Scotland John Swinney had already met Wu at Boston City Hall on June 12 — six days before the signing — to discuss strengthening economic and cultural ties, according to the research briefing.
There is also deep historical common ground. Glasgow officials specifically cited Boston's "Operation Ceasefire" — a 1990s gang-violence reduction program sometimes called the "Boston Miracle" — as a model they adopted in the mid-2000s. The April 2027 Tartan Day signing is expected to include university exchange talks involving institutions like Harvard, MIT, and the University of Glasgow, Fox Sports reported.
