Yes to what Historyenne said. Not sure about Tesco, but Morrisons & Sainsburys both carry (white) albacore tuna in the tin, in either water or in oil. That's what I buy. Sainsburys used to carry a really posh one in glass jars before they had it in the tins, but not sure if they have that one (Taste the Difference range albacore) any longer. The albacore is more expensive than the regular tuna, but worth it, IMO.
