The collapse of a deal for the oil refinery in Milford Haven is "very disappointing", David Cameron has said.
But the Prime Minister insisted ties should not be cut with Klesch Group, which is also in the process of buying Tata Steel's long products division.
Mr Cameron made the remarks in answer to Labour MP Tom Greatrex who highlighted concern about the Swiss-based firm's intentions given its record of "asset stripping".
Speaking at Prime Minister's Questions, Mr Cameron said, "First of all, let me agree with you it is very disappointing what has happened at Milford Haven and we will continue to work with the company concerned and try to find employment opportunities for all those that work there.
