My hon. Friend is right, and I will thank him properly on Third Reading, but may I just put on record at Committee stage my thanks to him for the work that he did chairing the Select Committee that looked into all of this? It did a thorough piece of work and I am hugely grateful to him and to colleagues who gave up so much of their time.
Yes, costs have gone up. I say this as somebody who has spent some considerable time looking at development costs in the private sector. Sometimes we can look at things in the public sector and say, “How on earth have they arrived at this particular figure?” But the National Audit Office, the Public Accounts Committee and others will keep a very clear view on that, and they are right to do so.
I say this to my hon. Friend: we want to commemorate and memorialise a horrible period in our world history, and ensure that education can be provided so that the mistakes of the past are hopefully not repeated in the future. I do not make this point to be flippant, but what cost can be put on that, given the scale and the seriousness of the task that we have in front of us?
