Available now, the grapefruit and citrus flavoured PPS comes in 275ml and 70cl bottles. The brand will be supported by a £10m marketing campaign with TV commercials featuring comedian Avid Merrion, which were launched last year.
Halewood International's marketing manager, Richard Clark, said: "Red Square enjoys popularity among both male and female markets in the 18 to 24 age group, although there is a slight bias towards men. Last year we introduced Red Square Black, which has been adopted by male drinkers, and we predict we will have the same impact with Pink among female drinkers."
The Red Square range, currently the fourth bestselling PPS, also includes the original Red Square Reloaded, Red Square Green with tequila and Mexican lime, and Red Square Purple Loganberry Ice.
