Vinci bid expected to win Portugal's ANA-sources

LONDON/LISBON Dec 27 (Reuters) - French construction group Vinci is expected to win a bidding race for Portuguese airports operator ANA, with a deal that could help indebted Portugal raise up to 3 billion euros ($4 billion), three people with knowledge of the matter said.

The people told Reuters on Thursday that Vinci had been chosen from four final contenders, including Fraport of Germany, Zurich airport operator Flughafen and Argentinian infrastructure group Corporacion America.

"The Vinci offer is so high that it was placed at the top of the list for the cabinet to evaluate. The preliminary evaluation was to recommend Vinci, for its financial bid and overall parameters. But the decision is with the cabinet," one of the people said.

Portuguese government officials said the cabinet was still in a meeting and had no immediate comment.
