@hawkeye10,
For a start your professor of European Studies does not quite back up what you say.
This whole thing happened with the relationship between Roop and Thatch. Thatch gave him control of 40% of the Media, and he supported her. The Sun is Britain's biggest daily, it's also got a reading age of about 8. It's readership is notoriously fickle/thick and easily swayed. Thatch came to power in 1979. The tories had the support of Dailys: The Sun, The Daily Mail, The Daily Express, The Times, the Telegraph and The Financial Times. Labour had the Guardian and The Daily Mirror. I'm not going to list Sundays but it's a similar story.
By 1992 there was a feeling of change. The labour leader, Neil Kinnock was ahead in the polls, The Financial Times and the Times (halfheartedly) had gone over to Labour. Even then Roop was hedging his bets. In the end the Tories won yet again. On election day The Sun ran the headline If Labour Win Today Will The Last Person To Leave The Country Please Turn Out The Light. This was accompanied by an unflattering picture of Kinnock inside a lightbulb.
Whether it was true or not, it was widely believed that The Sun clinched the election. The Sun believed it, the next days headline read It Was The Sun Wot Won It. Major's parliament started to ravel almost straight away, but by the time of the next election in 1997, the Tories had been in power for 18 years. A lot of people thought that a Labour victory could not be achieved without the backing of The Sun, so Blair courted Murdoch.
Murdoch is not a natural Labour supporter, but he backed the winning side and kept hold of the same sort of power and influence as he had enjoyed under the Tories. It wasn't a one-way street, Blair used Murdoch to win support for the Iraq war. Most Labour members hate Murdoch, as do the MPs. It was never an easy relationship, and it fell apart when Brown became prime minister.
Brown was not at all charismatic, and not only that he refused to scrap Ofcom and cut the funding of the BBC. Murdoch went over to the Tories, and Andy Coulson became Cameron's press secretary. When Cameron became prime minister Coulson entered Downing Street. Cameron has entertained, and been entertained by Brooks and Jimmy over the Christmas holidays.
The situation with the Met is different. The NOTW could always be relied on to plant positive stories about the police. The police would allow NOTW journos exclusive access to raids on criminals targetted by NOTW journos. You then have the attitude of certain high ranking police officers. They will have to answer for themselves, corrupt or incompetant.
So the situation is, certain high ranking officers in the Met, and maybe some less high ranking officers are in the frame. David Cameron's inner circle may be touched as well as other Labour ex ministers associated with Blair, and to a lesser degree Brown.
The vast majority of MPs welcome this. The British establishment isn't quivering, just a few choice individuals.
