A new Wild Berry flavour has replaced the Peach and Lemon variants in the Smint Mini Mint range.
Its arrival is heralded by a £3m campaign ­ the Chupa-Chups owned brand's biggest yet ­ which kicks off on TV screens on Monday (March 17), with ads focusing on its sugar-free benefits.
Taxis around the country will sport the same message, with drivers carrying samples.
Other sampling activity will take place in city centres, at football matches, train stations, bars, retail parks, restaurants and stores.
There will also be posters at London Underground stations.
Besides sugar-free status, the Wild Berry newcomer also boasts the full recommended daily allowance of Vitamin C in every pack.
