The Bratach Gorm (a.k.a. Blue Banner) is the highest prize given by the Scottish Piping Society of London and was introduced in 1938. It can only be won by those who have won the; Highland Society of London Gold Medal at the Argyllshire Gathering or Northern Meeting or the first prize at the William Gillies Memorial Cup. The monetary value as a primary Pibroch is £500. In 1994 the competition pool was further reduced in protest at the selection of judges. In order to win the annual London Piping Championship an entrant must have won this and another award.
