1 — a move that will dash the hopes of Britain’s Conservative government, which is anxious to show the importance of the session to the fate of the planet.
The queen underwent the medical tests after she canceled a scheduled trip to mark 100 years since the creation of Northern Ireland, and the palace said she had “reluctantly” accepted advice to rest for a few days.
Her doctors ordered rest last week after the monarch who likes to be seen by the people carried out a hectic series of events.
Days earlier, she was seen using a walking stick at a Westminster Abbey service marking the centenary of the Royal British Legion, an armed forces charity.
She is due to celebrate her Platinum Jubilee — 70 years on the throne — next year.
