Gatwick closed (now reopened) - aborted take off
All possible. However, instrument problems or unreliable speed would not require staying parked on the runway for 40 mins - unless possibly it was a hot brake issue from a high speed RTO, with a chance of the fusible plugs going and deflating the tyres.
Surely the B777 has brake fans ? Bit daft if they have to block a runway every time they have hot brakes.

There are hot brakes and HOT BRAKES! We had a hot brake on an A300 and when the fans were turned on one brake caught fire. It happened at EDI right outside the fire station.

No brake fans on a B777, the carbon brakes are very effective and under routine ops brake temperatures are rarely an issue.
Rejecting a takeoff in a 250T airplane from around 140kts at 200’ elevation +20°C is going to put you just inside the fuse plug melt zone and the QRH instruction reads…
“When in fuse plug melt zone, clear runway immediately. Unless required, do not set parking brake. Do not approach gear or attempt to taxi for one hour. Tire, wheel and brake replacement may be required.”
For whatever reason, whether external (Fire service or ATC request) or internal, captain’s decision, the crew elected to stay on the runway. Their prerogative and one that will be subject to scrutiny both within the company and outside through the AAIB. Doubtless learning points will come, but for now I think a high-speed RTO with a safe outcome is a good result.
