They have been advised that the £3.70-a-share offer recommended by the IDS board seriously undervalues Royal Mail if regulator Ofcom recommends changes to Royal Mail's Universal Service Obligation. This guarantees letters and parcels are delivered six days a week across the UK at a fixed price, which Royal Mail says is a drag on its loss-making business.
