Leading corporation, lift prize (7) J?C?P?T
Jackpot fits at least three-quarters of the clue but I can't see the 'Leading' element of the clue. Any help gratefully received....
Help please: "What's taking place brielfy in sanctum - glorious little mass" (9). M?L?I?R?M. I assume that the answer is milligram (little mass) but I can't see how the rest of the clue fits....
