Pelosi, 84, is “currently receiving excellent treatment from doctors and medical professionals”, spokesperson Ian Krager said in a statement.

The Democrat, who still represents California in the US House, was travelling with a bipartisan Congressional delegation to Luxembourg to mark the 80th anniversary of the Battle of the Bulge.

Krager said Pelosi “looks forward to returning home to the US soon” and continues to work from the hospital.

The San Francisco congresswoman resigned from her position as speaker, an influential post second in line to the presidency after the vice-president, in 2023 after two separate four-year terms in the role.

But she has continued to serve in the House. Last month, she was elected to another two-year term.
