Wrong about the reasons
The Daily Mail aren't in a position to be investigated by Ofcom about expanding their ownership of media.
Monetary crises are the Daily Mails stock in trade - they'll always run a story on a subject that might affect house prices in England, doubly so if its origins might be the financially illiterate foreigners - whether to divert attention or not.
They might well have indulged in dubious practices of the sort carried out by NI, but so far they've either been more selective or secretive compared to Wapping and are for the moment out of the spotlight.
Perhaps when the police have been able to interview the legmen satisfactorily, their other clients will come to notice and the full glare of the public's ire turned on them too.
And if you think the Guardian group are nobler then the other Fleet Street denizens then you are sadly misguided. Hacks or champagne socialists - the lot of them.
