British parliament speaker: Queen in our prayers

STORY: "I know I speak on behalf of the entire House when I say we send all the best wishes to her Majesty the Queen," Hoyle said after interrupting a debate.

Leader of the SNP in parliament, Ian Blackford also expressed concern, saying "the thoughts and prayers of all of us will be with Her Majesty the Queen and indeed with the Royal Family".

Family members rushed to be by the side of the 96-year-old monarch after the doctors announcement, which said she should remain under medical supervision.

The queen, Britain's longest-reigning sovereign and the world's oldest monarch, has been suffering from what Buckingham Palace has called "episodic mobility problems" since the end of last year.
