The Mirror says:
In yesterday's Daily Mirror newspaper a picture captioned Great Britain's gold medal winning dressage team was in fact of the Dutch bronze medal trio.
We apologise for the mistaken use of the picture, which was supplied by a normally reputable agency.
The Express has published an article about dressage - 'the sport riding high' - which ends with:
Due to a caption error by a picture agency, some editions of yesterday’s Daily Express showed a photograph of the bronze medal-winning Dutch dressage team instead of the victorious British dressage team. We sincerely apologise for the error.
