Ah well now! On the subject of Radio 4, I have given up trying to point out that it is laziness to use an apostrophy smeaning 'has, and making it sound like 'is', thus changing the meaning....
Example:
... the PM's arranged a meeting...
It sounds like: the PM.is instead of, as it should, the PM has
Okay it doesn't happen every time, but too often for comfort!
