There is no formal assessment. However, the new approach appears to be working well.
May I urge the hon. Lady to undertake an assessment to highlight some of the problems that we are having with topical questions? For example, under the old system, in any typical 60-minute departmental Question Time each Member of this House had the opportunity to ask one question. Now, it is increasingly the case that some Members get the chance to ask two questions, while others lose out altogether.
Obviously, who is called during topical questions is a matter for the Speaker. However, I think that there was a consensus that the introduction of topical questions would help to ensure that questions that had arisen very shortly before Question Time could be answered fully. Notwithstanding the points that the hon. Gentleman makes, by and large most hon. Members are happy with the current practice.
