Its report was presented to the Postmaster-General on 23 February 1924 The committee's recommendations were similar to those of the Norman Committee – that any stations in the United Kingdom used to communicate with the Empire should be in the hands of the state, that they should be operated by the Post Office, and that eight high-power

It therefore recommended that the cable and wireless interests of the

An expert committee also advised that Marconi were the only company with technology that was proven to operate reliably over the distances required (in excess of 2,000 miles (3,200 km)) "if rapid installation and immediate and trustworthy communication be desired".

Due to such factors Cable and Wireless were never able to earn the revenue which had been forecast, resulting in low dividends and an inability to reduce the rates charged to customers as much as had been expected. To ease the financial pressure, the British Government finally decided to transfer the beam stations to Cable and Wireless, in exchange for 2,600,000 of the 30,000,000

Wireless and Cable Conference" was therefore held in London in January 1928, with delegates from the United Kingdom, the self-governing Dominions, India, the Crown Colonies and Protectorates, to "examine the situation which arose as a result of the competition of the Imperial
