20a. They might have been of interest to Mr Philip Attlee in short - or so it is said. (6) _ T _ M _ S.
Could it be Stamps, or maybe Stumps.
I know that Atlee (without the double 't') was an MP and was an avid cricket fan. Also his image is/was on postage stamps. So, I am stumped!
You're welcome fuzzy. Sorry I made such a mess of it. I was slightly wrong. The clue says Philip Attlee in short so it would be Phil Attlee, which then sounds like philately.
