161 In each of these examples, the bracketed clause is a control clause containing a PRO argument. In each case, PRO is the thematic complement of a passive participle (viz. betrayed/indicted/accused). Hence, if control to has no [EPP] feature and PRO remains in situ, the TP in the bracketed infinitive complement in (46b) will have the skeletal structure (47a) below, but if control to has an [EPP] feature, this will trigger movement of PRO to become the structural subject of to – as in (47b): (47)(a) (b) [CP [C ø] [TP [T to] [AUXP themselves [AUX be] [VP [V indicted].
