BRUSSELS, April 9 (Reuters) - EU antitrust regulators have not sought feedback from rivals and customers on remedies submitted by British Airways owner IAG for its deal to acquire Air Europa, indicating that these are insufficient to address regulatory concerns, people with direct knowledge of the matter said.

The European Commission, which acts as the EU's competition enforcer, is due to issue a statement of objections to IAG around the end of April, setting out specific concerns that could lead to a veto of the deal if not addressed, the sources said.
