Queen seen walking her dogs after 'showing slight signs of a cold'

Queen Elizabeth has been seen driving her Landrover and walking her dogs on her Windsor estate on Wednesday, after being forced to cancel a trip to Northern Ireland.

The 95-year-old monarch was ordered to rest by doctors after "showing slight signs of a seasonal cold", according to UK newspaper The Mirror.

The publication reports Her Majesty, who has had quite a number of public engagements already this month, was reportedly feeling "a little tired" on Tuesday evening after hosting a reception at Windsor Castle for the Global Investment Summit.

It's understood royal doctors were called to Her Majesty's living quarters, after which they ordered a period of rest.

The Queen had "reluctantly accepted medical advice to rest for the next few days" and "is in good spirits" Buckingham Palace said in a statement issued on Wednesday.

They didn't reveal the cause behind the medical advice, only that it's not COVID-19 related. No further updates on Her Majesty's condition have been provided since.

However, multiple media outlets have quoted sources saying there is "no cause for alarm" regarding the 95-year-old's health.

The Queen was "disappointed" to have to cancel the two-day trip, which was filled with events to mark the centenary of partition in Northern Ireland.

Despite her age, Her Majesty shows no signs of scaling back her schedule, which could be down to her motto of "you are as old as you feel".

The quote came to light earlier this week when the 95-year-old turned down the title of Oldie of the Year, saying she doesn't meet "the relevant criteria".
