Today's appearance from Pfizer bosses before MPs "confirms many of the worst fears" about the proposed takeover of AstraZeneca, Labour have said.
Shadow Business Secretary Chuka Umunna told the BBC: "What we heard at the hearing today reinforces the grave concerns we have about this deal and confirms many of the worst fears of people in the business and science community in the UK.
"What do we know? They confirm that they will be cutting jobs. They confirm that there will be a cut in the spending of the combined merged entity. They've confirmed that the business, AstraZeneca will be split up, and they haven't ruled out selling off parts of it in the future.
This morning Pfizer has "gone hostile", not with a renewed bid but with an appeal made directly to the shareholders of AstraZeneca.
MPs on the business committee are sceptical that AstraZeneca would remain committed to Britain if taken over by US giant Pfizer.
