For Maizie, and Dinah, any others concerned by a supposed Middle Eastern editorial desk on one of our (allegedly) more influential newspapers, Ronib has the correct angle, the circulation is on the decline, as it has been for years, and so is the strong trend for all print media. The last time I looked, the Metro (given away on buses), had the biggest daily circulation.
Every election I like to correct people who start squawking about the nasty Tory Press (if they're Lab voters), or how the biased Lefty Mirror and Guardian are telling lies about Tory policies (etc). Those few people who still buy a paper (or these days shell out for a digital version) invariably choose their paper because it ALREADY does what THEY like. People who buy Telegraphs, the Mail and Express are hardly likely to be about to flip to Labour. Those buying Guardians and Mirrors aren't likely to be swayed into getting Blue rosettes anytime soon? I'm informed that for serious sports fans, the Telegraph has by far the best sports section, with a host of (mostly) male readers looking at that, not any right-leaning editorials in the earlier pages.
Anyone buying a paper has to consider giving its remaining readers what THEY want, not what YOU want to sell them, else they'll desert it and your investment looks worse. Maybe check out who owns the Express, the same group as own the Mirror (& others), but the Express still churns out the same stuff, what THOSE readers want to see.
As Ronib said, the overall circulation has plummeted in the last 20 years, the Press has had far less influence than people realise, and for quite some time.
