During the first session of Treasury Questions since the re-shuffle, I welcomed the Chief Secretary back to his place and commend to him last year’s “Building Great Britons” report by the all-party parliamentary group for the first 1,001 critical days, which I chair. 

The report revealed that the cost of getting it wrong on perinatal mental health and child neglect is some £23 billion. 

I asked him whether he agreed that investing in young people at an early stage is every bit as beneficial to the economy as investing in roads and infrastructure.
