L'indépendance Luxembourgeoise - Queen calls off meeting after 'full day' for UK's new PM

"After a full day yesterday, Her Majesty has this afternoon accepted doctors' advice to rest," the palace said in a statement.

"This means that the Privy Council meeting that had been due to take place this evening will be rearranged."

The 96-year-old monarch, who is currently on her traditional summer retreat at Balmoral in the Scottish Highlands, has been dogged by problems walking and standing since last year, forcing her to cancel a series of public engagements.

Fears about a flare-up of what royal officials call "episodic mobility problems" prevented her returning to London to accept outgoing leader Boris Johnson's resignation and to appoint Truss on Tuesday.

The constitutional role -- the so-called "kissing of the hands" ceremony -- usually takes place at Buckingham Palace in London.

It was the first time it had been held outside London since 1952, when Winston Churchill met the new queen at Heathrow Airport after the death of her father, George VI.

Meetings of the Privy Council, a kind of royal advisory body dating back hundreds of years and comprising hundreds of members, including religious and political leaders, usually happen monthly.

Wednesday's scheduled virtual event would have seen Truss take an oath and new cabinet ministers sworn into their roles, and also admitted new ministers to be privy counsellors if they were not already.

Last week, Britain's longest-serving monarch skipped the Highland Games event, a traditional highlight of her summer in Scotland.

The latest cancellations will revive concerns about her health.

She has cut back on public engagements since last October after an unscheduled overnight stay in hospital for an undisclosed condition.

She was also hit by a bout of Covid earlier this year, that she said left her "exhausted".
