Royal Mail workers will be offered a 10% stake in the company as the Government steps up plans for a flotation amid a recent rally in financial markets, according to reports.

Ministers are in advanced talks about giving the shareholding to staff at Royal Mail, who could be offered attractive incentives to buy shares or even be offered them for free, reports claim.

The privatisation will be the country's biggest for more than 25 years, since the British Telecom and British Gas shares sales in the 1980s.

It is thought recent gains seen on the FTSE 100 Index – which enjoyed its best January for 24 years – has spurred on plans for a flotation.
