In 1614 Whitelocke was re-elected MP for Woodstock in the Addled Parliament. He was nominated with Sir Thomas Crew and others to represent the Commons in the projected conference with the Lords. Because of the sudden dissolution on 7 June the conference never met and on the following day Whitelocke and his colleagues were summoned to the council chamber, and told to destroy the notes of their intended speeches. In disfavour at court, Whitelocke was compelled to surrender (18 November 1616) the reversion of the king's bench enrolments' office which he held jointly with Robert Heath, by whom he was also defeated in the contest for the recordership of London in November 1618.
