Once upon a time, broadcasters on the BBC were noted for the clarity of their speech. Sadly, those days appear to be well and truly over - I've noticed of late there are two particular mispronounciations that are occurring with ever-increasing frequency:
1. Properly is often pronounced as "proply"
and
2. Police often sounds more like "pleece"
I know that English is an evolving language, but this isn't evolution - it's just sloppiness.
