ASDA entered the cola wars yesterday with the launch of the ''first

fully UK premium cola''. The supermarket chain says its latest own-brand

drink is the only cola invented, produced, and canned in the UK. Earlier

this year, Sainsbury dramatically raised the supermarket cola stakes

with the launch of Classic Cola. The move irked Coca-Cola which insisted

that the superstore altered the design of red and white cans because it

felt consumers were confusing Classic with ''the real thing''. Asda said

its new cola also came in red and white tins -- but stressed they were

not meant to be ''lookalikes''.
