When an individual takes the lead he pips the rest of the field, pip would only fit if there was more than one taking the lead. I'm not sure about PPS for Francis Maude (a position he held a long time ago), but pope doesn't fit particularly well with clue either.
I took the definition to be: one Francis ( someone named Francis) e.g. the newly elected Pope.
I thought the comma was meant to mislead.
Maude (finally) = e + pop(abbrev. for popular)
I think maybe I've lost the plot ?
