Oliver visited DoubleTree by Hilton London Elstree to meet the Ukrainian refugees taken in by the hotel.
Lethendy Estates Ltd., which owns the Hilton in Elstree, is providing accommodation, food, and essential items, free of charge, to refugees fleeing Ukraine.
Oliver visited the hotel to meet its staff and speak to the refugees about their experiences.
Oliver said: 'It was a pleasure to visit Hilton Elstree to meet the Ukrainian refugees who have been generously taken in by the hotel.
As Putin continues to wage his war of aggression, we must be open and generous in welcoming to the UK those who have tragically been forced to flee their home country.
I was pleased to see first-hand the hard work of the staff at Hilton Elstree and hear from the refugees about their experiences. I wish them all the best as they begin to rebuild their lives here in Hertsmere.'
