The government has given formal notice to the London Stock Exchange that it plans to privatise the Royal Mail in the coming weeks.
The sale of the business, which is worth around £3bn, is expected to take place in November.
Business secretary Vince Cable said: "HM Government is taking action to secure a healthy future for the company."
However the Communication Workers Union (CWU) opposes the float and is expected to vote for industrial action - the first date available for a strike is 10 October.
