I'm afraid that I know nought about the left-wing credentials of the city analyst mentioned here...
Royal Mail worth 82% more than government's valuation, analyst claims
Shares in the privatised postal service could be worth 599p - a hefty premium on the likely 330p flotation price
"Royal Mail could be worth as much as £6bn, almost double the government's maximum valuation, according to a City analyst.
The valuation by stockbroker Canaccord Genuity was the second to say the government had seriously undervalued Royal Mail, potentially shortchanging taxpayers by more than £1bn. It came as ministers held an emergency meeting to decide how to share out Royal Mail's shares following overwhelming demand from the public, City investors and pension funds. It is understood David Cameron will make a final decision on Thursday afternoon.
Canaccord said it believed the government could have sold Royal Mail shares at 599p, 269p more than the shares will be sold at when the company floats on the stock market on Friday morning..."
