[Matakari]

Good morning, Doc’s offering for this week seems quite simple with a somewhat mysterious theme, but I’m still stumped by two clues for which I would appreciate answers with parsing, thanks!
30 ( A ) Runs by Hassett regularly upset old emperor (4) : ???R ( TSAR )
34( A ) Key that’s silver every so often (4) : IS??

Tsar and Isle

[jazzgirl]

34 key isle
every other letter of "is silver"

[jazzgirl]

tsar r (runs) + every other letter of hassett (in reverse)

Matakari, the 'mysterious' theme has appeared in quite a few crosswords over the years.

Thanks, all, it's done now. And the theme was not as mysterious as I first thought. In fact, it turned out to be very easy, indeed!

[aelmpvw]

30a tsar, t s a from Hasset backwards + r (runs)

i'm sure when i clicked on this question there wasn't an answer?

Glad you got there in the end, Matakari - though disappointed that you didn't have another completed (unaided) Doc to add to your growing collection!
