Sadiq Khan met hundreds of young people of different faiths and backgrounds at Chicago’s oldest synagogue during a tour of America.
The Mayor of London shared his views on how international communities can work together to promote social integration and tolerance across the globe.
The Mayor was pictured taking selfies with faith leaders and those who turned out to greet him.
He said: “London is an incredibly diverse and tolerant city, but improving social integration is still one of the big challenges we face.
“That’s why I’m keen to hear from people of many different faiths here in the US to learn from their experiences and to share ideas on how we can bring communities together and strengthen the social fabric that underpins any successful city.
“I also want to tell everyone around the world, loud and clear, that London is open to people of all faiths and backgrounds.”
Last week, Matthew Ryder was appointed deputy mayor for social integration, social mobility and community engagement.
Mr Khan asked Matthew, a leading QC, to help ensure Londoners from different faiths, ethnicities, backgrounds and social classes are better integrated into the capital.
