Dave Ward, deputy secretary of the Communication Workers Union, said the continued inflation of Royal Mail shares show the 500-year-old institution was sold on the cheap, with the taxpayer losing "over a £1 billion" to the "government's city mates."
Ahead of the result of tomorrow's ballot for strike action, he said:
"The Royal Mail share price has soared further today, bringing more proof that the company was undervalued by the Government's City mates.
"The taxpayer has lost over £1 billion already in this bungled fire sale of a cherished national institution. Postal workers cannot trade their shares for three years and they are far more concerned about their jobs than the share price."
