Halfway through this and I'm stuck.
21 A. Transactions seen in trade empire also (6) ??ea??
34 A. Theologian capturing English cathedral city's exalted stone (6) ??see?
There MAY be an additional word, not needed for solving, in the clues.
21A I think the answer is "deals". Empire is the superfluous word, yielding ee as the 2 letters.Only 5 letters long so this must be one of the discrepancies to be resolved.
