Irn Bru have unveiled an hilarious new advert which tells the story of an embarrassing moment on board a busy train.

The advert shows in Irn Bru's classic tongue-in-cheek style how the lad,who is caught on the toilet as the door opens on a train, uses Scotland's national drink to get him through the embarrassment.

The Gets You Through campaign, now in its fourth year, is the brand's most successful to date with previous ads including Steamy Windows, Blind Date and Fanny generating 10 million online views.

Train will be previewed on irn-bru.co.uk/train and official Irn-bru social channels from today and will air on TV screens across the United Kingdom on tomorrow.

Adrian Troy, Irn-Bru Head of Marketing, said: "Our Gets You Through campaign reflects the uplifting qualities of IRN-BRU and Train shows that despite life's ups and downs, we can always retain a sense of humour and get back on track!"
