British racing will come to a halt on Wednesday as the sport seeks to demonstrate its opposition to proposed betting tax changes.

It was announced last month fixtures scheduled for Carlisle, Uttoxeter, Lingfield and Kempton would be cancelled as racecourses, owners, trainers and jockeys voluntarily refused to race for the first time in modern history in protest at suggestions the existing three-tax structure of online gambling duties could be condensed into a single tax.
