Spanish dairy company Clesa has rejected reports that bankrupt parent Parmalat is looking into selling it to local investment family Ruiz Mateos.

A Clesa official said the report in financial daily Expansion was "completely false." She reiterated prior company assertions that Parmalat's legal woes will not affect the Italian dairy group's 100% Spanish subsidiary. Clesa has always maintained separate accounts and commercial channels, the spokeswoman explained.

In other developments Clesa, which has factories in Leon and Burgos, Northern Spain, said it launched a new line of functional yoghurts called Activ Soja. The company makes milk, chocolate drink Cacaolat and other dairy staples.
