My hon. Friend is doing an excellent job in making the case. Does she accept that the information that is available to the House through the various bodies and institutions that my hon. Friend Steve McCabe mentioned is massively undermined by the number of non-disclosure agreements that have been applied to former members of staff of HS2? More than 270 NDAs prevent people from saying what they really believe about the capacity and costs of the scheme. What does she think about that in terms of transparency and openness?
