Tommy Fleetwood, Viktor Hovland and Andy Sullivan shared the lead at the BMW PGA Championship after a sombre first day at Wentworth Club.
The Ryder Cup trio carded rounds of 64 to get to eight under before play was suspended after Buckingham Palace announced the sad death of Her Majesty Queen Elizabeth II at the age of 96.
No play will take place on Friday, with further updates on the resumption of play to follow in due course.
England's Matthew Jordan was at seven under, a shot clear of countryman Marcus Armitage, Ireland's Shane Lowry, Australian Jason Scrivener and Paraguayan Fabrizio Zanotti at the fourth Rolex Series event of the DP World Tour season.
Scotland's David Law was three shots off the lead alongside Dane Rasmus Højgaard, who had one hole left to play before the players came off following the announcement of the passing of the UK's Head of State, who had been on the throne for over 70 years.
In his first start since The 150th Open, Fleetwood picked up shots at the second and the fourth before a strong finish on the back nine. He birdied six of his final seven holes, the pick of the bunch a 26-foot putt dropping at the 16th.
Hovland, a Rolex Series winner this season in Dubai, went birdie-birdie-eagle from the 16th - holing from 17 feet, 10 feet and then capping it off with a 27-footer in front of the grandstand on the final hole.
Sullivan recovered from an opening bogey to turn a couple under and then managed six birdies on the way in - including a 34-footer at the 17th which saw him join Fleetwood at eight under.
The four-time DP World Tour winner set up a birdie putt opportunity from six feet at the 18th but missed the chance to take the outright lead.
