Willie Mullins will become the first Irish trainer to run a horse in Britain since Brexit, following an early morning precautionary inspection at Market Rasen.

Although raceable on Friday, a forecast of potential wintry showers had put the Lincolnshire venue on alert ahead of one of its biggest days of the calendar.

The feature Alan Swinbank Mares' Standard Open National Hunt Flat Race sees the Mullins-trained Grangee clash with Pam Sly's also-unbeaten Eileendover.

There are no reported problems for the Classic Chase card at Warwick, while jumps action also takes place in home in Fairyhouse, where impressive Cheltenham winner Chatham Street Lad headlines the Dan Moore Handicap Chase.

The going at Market Rasen is heavy, with Warwick soft, heavy in places on the chase track and heavy, soft in places on the hurdles course. It remains heavy at Fairyhouse.
