Corbyn couldn't say how much childcare policy would cost.
Pretty incompetent, surely they should all have learned by now that when you make a spending commitment you need to be able to say:
1. How much it will cost
2. Where that extras money is going to come from
That said, I can't help laughing on this issue (or maybe crying) given that I part own a nursery which would have to deliver the 'free' child-care. And by free what that actually means is that the nursery receives a set rate of funding per hour from government (via local authorities), which is dependent on the nursery offering that place to parents free.
So the Tories have played this game too - in their 2015 manifesto they committed to providing 30 hours 'free' - currently it is only 15 hours. Did they cost this up - did they heck. This is to be rolled out in September this year, and therefore it is critical that nurseries know how much they will receive for each 'free' hour (which by the way is way less than they would otherwise charge) as this makes the difference between running a viable or non viable business.
Ever since the election in 2015 we have been trying to get clarity on the rate, so we can model and plan for its effect. The rate (and therefore the cost of the manifesto pledge) was only confirmed in late March this year - some 2 years after it was put in their manifesto.
Point being that it is easy to throw some ill thought out plan into a manifesto - but not only do you need to cost it, you also need to assess its impact on businesses and individuals who will be affected by its implementation.
