Theresa May and Boris Johnson secrecy as statecraft?

During UK–EU Brexit negotiations, Theresa May pursued a determined path of concealment and non-disclosure. Envisaged as a way to protect herself against political opposition, enhancing her bargaining power vis-à-vis the EU and deliver policy promises, the strategy failed and contributed to the end of her premiership. Ben Worthy and Marlen Heide detail how her case illustrates the powers of increasing transparency expectations and the risks of concealment over longer times or around contentious issues. It provides a useful lesson for her successor.
