I'm no fan of the Daily Mail but to be fair to them, their website often has coverage of Camilla's engagements - far more than the Daily Telegraph's. Their articles (except Richard Kay/Geoffrey Levy's) have also been quite positive in recent months.
As you say, it's lovely to see so much of Camilla. She has noticeably increased her workload this year
The Daily Mail website that you can access may well have coverage of Camilla's engagements but the actual hardcopy published in the UK (especially outside the south-east of England) quite often doesn't have the articles that are 'published' online. So the people outside the UK (who don't vote in UK elections or get sounded out in UK opinion polls) get a better idea of her engagements than those in the UK!
