A man dressed as a jockey had to be escorted away from the parade ring at Newbury on Friday whilst The Queen was there celebrating her 91st birthday.
The man, who is believed to have been on a stag trip, entered the secure parade ring ahead of the 3:05 race – a race in which Her Majesty had a runner.
Head of Communications at Newbury Racecourse, Andy Clifton said: “A guy who appeared to be on a stag do tried to walk into the parade ring with the jockeys and was politely asked to leave by Julian, who apprehended him.
“There was nothing sinister about it, but when the Queen is here these things need to be taken seriously.”
The 91-year-old monarch was not in the parade ring at the time as she was dining in the Royal Box.
Horse racing is The Queen’s favourite past time, so it is no surprise that she had chosen to spend her 91st birthday at the racecourse.
Her Majesty did have a runner in the third race of the day, Maths Prize. However, there was no birthday look for The Queen as her horse finished fifth place in a field of six.
Princess Anne joined her mother at the racecourse to see Maths Prize attempt to win the Dubai Duty Free Golf World Cup EBF Stallions Conditions Stakes.
Elsewhere in the country, military salutes were held across the UK to mark the occasion of the monarch’s birthday – including a special 21-gun salute at Windsor Castle where children fired tiny cannons.
The bells of Westminster Abbey rang to mark the occasion, and the Irish Guards performed a special rendition of Happy Birthday to You outside Buckingham Palace.
