Last 3 clues leave us puzzled!
20d. Single-issue college speakers get up briefly (9). U?I?A?O??
Uniparous, but why?
26d. State funds partner no longer one with place on the board (9). I?C?E???R. Only word that fits is ‘Increaser’?.
40ac. Take The Sun for understanding article on woman (6). B?S???
Strange words, many of the clues though! Why, for example, is 24d (Callixenus comprehends his limits age wise) Quinquagenarian?
Many thanks.
