A couple visiting London on their honeymoon said they found out the Queen had been taken ill during their tour of the palace.

“It’s quite sad,” newlyweds Neil Patel and Kelly Powers told The Independent. “We were inside the palace on the tour when we get the notification on our phone - it’s quite an eerie feeling.”

“When we heard the news it fell on us like a ton of bricks,” the family said. “Not only is the weather grey but the mood is solemn. Even the workers inside told us on the way out of the tour - they seemed sad and worried.

“We love the queen. We have become Anglophiles very quickly. We’ve been coming here for over 10 years. We didn’t come for the Jubilee but we’re here now.

“It’s shocking she’s been around for so long she looks so healthy she just welcomed a prime minister.

“In our lifetimes we’ve never seen a king - we don’t know anything else.”

“It’s very sad because we’re here in this moment,” he said. “We came to the palace so to hear this is very sad. I love Britain, I love the royal family - I come here six or seven times a year.

“It’s hard to say all the feelings because we just heard about it a few minutes ago but you can tell the atmosphere here is very quiet. It feels very respectful.”
