I'll try to avoid party political arguments, but all governments have to deal with the mistakes of their successors, in this case tragic errors in making laws and building regulations. That goes with the job, and in this case it's not particularly unfair because May, as a previous home secretary, does have to bear some responsibility.
But she's not responding personally in a way that encourages people. A century ago, a prime minster would never have to meet the common people. Now it's part of the job; and they want you to look empathetic as well (as the Queen found with Diana's death). May hasn't really got the common touch. As I've said before, I'm not bothered whether she meets survivors or not; but the public seem to mind and her party probably do too. She should really have known this before applying for the job. Blair and Cameron had it; Gordon Brown was another one who didn't.
