28a Gremlin (troublemaker) - 'K(ing)' leaves 'Kremlin'...
21d Orwell - 'we' (in) o(ld) + r(are) + ll (leaves, as pages)
25d Mere - double meaning

[writesbad]

LIK - "ll" abbr. for "lines" perhaps?
All the best

Quite right, writesbad - my apologies! I was typing while trying to watch the match & not concentrating properly...

Thanks everyone!

Don't mention it, LIK. You are always generous with your explanations.
Who are you cheering on?
