Friday's play at the BMW PGA Championship has been suspended following confirmation of the death of Queen Elizabeth II.
Her Majesty passed away at her home in Balmoral on Thursday at the age of 96.
Play was immediately suspended at Wentworth once the news came through at 18:30 BST.
In a statement released later on Thursday, event organisers paid tribute to the Queen and confirmed there will be no action on Friday as a mark of respect.
"On behalf of our members and everyone associated with the European Tour group and the BMW PGA Championship, it is with great sadness that we have learned of the passing of Her Majesty Queen Elizabeth II," the statement read.
"She truly was an inspiration to people the world over. Out of respect for Her Majesty and the Royal Family, play has been suspended at the BMW PGA Championship at Wentworth Club for the remainder of Thursday and all flags at Wentworth Club will be lowered to half-mast.
"Furthermore, no play will take place at the BMW PGA Championship on Friday and the golf course and practice facilities will be closed. Further updates on the resumption of play will be provided in due course. Our deepest sympathies and condolences are with the Royal Family at this time."
Tommy Fleetwood, Andy Sullivan and Viktor Hovland held a joint-lead with an eight-under par 64 when play came to a stop on Thursday.
The tournament was scheduled to conclude on Sunday.
