This is all very unusual! An "unsolicited" take over offer is received and accepted by the board. The share price remains well below the offer price. Then out of the blue the offer is withdrawn! Wasn't the offer genuine? Has Meijen found something they didn't like during due diligence? How will this affect the 70c options which are due to be exercised before 2nd November - 3 days time!! The company has some explaining to do I think.
