The owner of Royal Mail has backed a £3.5bn offer for the postal company from a Czech billionaire after he sweetened the value of his planned takeover, creating a political headache for the government.
Last month, Royal Mail’s parent company, International Distributions Services (IDS), rejected a preliminary offer worth 320p a share, or £3.1bn, from Daniel Křetínský, the part-owner of West Ham United whose company, EP Group, is the postal service’s shareholder.
