U.S. superstar Taylor Swift's "unexpected" donation to Britain's Trussell food banks will have a nationwide impact, according to one of the charity's directors.

The 34-year-old singer made a "generous donation" to 1,400 food banks across the U.K. and community organizations in Edinburgh, Liverpool, Cardiff and London – the cities where she performed her record-breaking Eras Tour this summer.

Trussell director of public engagement Sophie Carre said Swift, who became the first artist to play London's Wembley Stadium eight times on the same tour, helped the charity at an "incredibly important time" when it expects a "huge number" of people to turn to it for support.

She told the Deutsche Presse-Agentur (dpa) news agency: "We weren't expecting it, but obviously we were really delighted when we found out.

"I think you never know about something like this, and we were very excited when her team got in touch.

"It's a really nice opportunity to make a local impact, but know you're part of a national cause and you can see the impact nationwide as well. It's great that it's an opportunity to connect that local and national impact."

Carre said Swift had helped highlight the charity's work.

Asked whether the singer's gift has prompted others to donate, she said: "I haven't seen anything to that effect at the moment, but I know that it's really helpful she's put a spotlight on Trussell and our food banks.

"Particularly at this time, as we face winter and the incredible levels of need that we know the food banks will need to meet.

"It really makes a difference, and hopefully, it will encourage others to support us if they can and play a part in it.

"We're certainly hoping that it helps encourage people to learn a bit more about us and get involved if they can."

Trussell did not disclose how much Swift donated, but Carre added: "We are incredibly grateful to Taylor Swift for her generous donation to Trussell.

"We are delighted that she has chosen to support the work of food banks.

"This, alongside the other donations she has made directly to food banks across the country, will help people facing hunger and hardship during their toughest moments while working towards a more just future where everyone can afford the essentials."

The donation will go directly to food banks through the charity’s emergency grants program, which supports the community initiatives that are most in need.

Trussell describes itself as an "anti-poverty" charity with a community of food banks that work together to provide emergency food and practical support for people left without enough money to live on.

Swift's Eras Tour will continue in Canada until Dec. 8.
