Tricky today. As usual I'd appreciate some help with parsing.
10a. Company managed decline, losing large frequency. (9) incidence? I can see decline without the L but not the rest.
12a. One dispute, a perfect example, beset by hollow scorn. (13). Disparagement?
7d. Part from emperor endlessly breaking agreement. (11). Constituent?
13d. Conceal pressure on places in film scripts. (11). Screen plays? Part of it seems to be an anagram. Thanks!!
