True Rule 4 stories
Real cases, in short. Each links to where it was reported.
Lingfield, 14 August 2020: 50p off a 16/1 winner
Two horses were withdrawn before a handicap, the 6/5 favourite and an 11/1 shot, but the information was not passed on properly and both stayed in the betting. Winning backers of the 16/1 winner Thechildren'strust faced a combined deduction of 45p plus 5p: 50p in the £. In effect a 16/1 winner paid about 8/1. The BHA and the racecourse group said they would look into why the withdrawals were not circulated. It is the biggest real deduction we found. Racing Post.
Stratford, 9 June 2017: the favourite that would not start
The evens favourite refused to line up and was withdrawn at the start. The 14/1 winner, Numbercruncher, carried a 45p deduction. His owner-trainer-rider had held a trainer's licence for only three days. Racing Post.
Nottingham, 3 October 2018: the wrong horse withdrawn
A 9/1 chance fell in the stalls, but the wrong number was radioed and a 33/1 horse was announced as the withdrawal. The stewards let it stand. The winner, a 7/2 joint favourite, took only a 10p deduction on bets struck before the new market formed, but the owner was furious and the BHA promised a review. Racing Post.
Galway, 2 August 2025: the deduction that never happened
An Irish case that went the other way. A horse was withdrawn at 3.40pm but announced to the course at 3.46pm, so bookmakers paid out without the 10% deduction. The IHRB accepted the announcement was an error. Irish Racing.
Wolverhampton, 9 January 2015: the price that moved by one step
A trainer who had backed one horse told Ladbrokes that his stablemate, Tango Sky, would be withdrawn. Ladbrokes' trader cut Tango Sky from 7/2 to 3/1, which moved the deduction on earlier winning bets from 20p to 25p. The Gambling Commission's July 2018 statement says the trader deliberately shortened the price to maximise the deductions, that Ladbrokes had not trained its staff properly, and that Ladbrokes first gave the regulator inaccurate explanations. The Commission wrote to Ladbrokes with advice; the Racing Post reported no fine. It told operators to write their Rule 4 rules in plain, accessible language, and warned it could require, by licence condition, that Rule 4 be applied on either the withdrawn horse's price when the bet was placed or its official withdrawal time recorded by the BHA. Ladbrokes now suspends the market, with no price changes, if it gets such information. The trainer was fined £3,000 by the BHA. The gain to the bookmaker was tiny (one writer put it at £7.70). The point is the incentive: a band step can be worth moving a price for. Gambling Commission, Racing Post.
The Derby, 6 June 2026: a non-runner declared after the race
The 3/1 favourite finished tenth after a hind leg caught in the stalls. About 20 minutes after the race the stewards declared him a non-runner. Bets on him were refunded and winners of the 7/1 winner Christmas Day faced a 25p deduction unless the bookmaker waived it. Ladbrokes and Coral did; others applied it. Entain's Simon Clare called the ruling "self-sabotage" and said the waiver cost hundreds of thousands of pounds. The BHA defended the stewards. The row shows that what you are paid can depend on the bookmaker's goodwill, not just the written scale. Racing Post, Irish Examiner.
Lingfield, August 2016: when a deduction helped
A three-runner novice race became a match when the 11/8 horse was withdrawn. The 4/6 winner's backers were reported to be better off under Rule 4 than a reformed market would have left them. Racing Post.
Forum allegations that individual bookmakers shortened prices just before withdrawals are not reported here: we could not verify them.
