One month after John West announced it was rolling out its No Drain concept across its entire tuna range, rival Princes is stepping up innovation with a flavour-infused range.

Princes is launching Infused Tuna into Tesco from next month in lemon & cracked black pepper, chilli and basil flavours (rsp: £1.45 per 160g can).

"Value-added tuna has traditionally focused on salads and lines like mayonnaise and sweetcorn," said marketing director Ruth Simpson. "We saw an opportunity to drive more consumers into this area."

John West launched Tuna with a Twist in 2001.
