Myths about Public Spending under Labour

I like this post and chart in Red Brick by Steve Hilditch about actual public spending as percentage of GDP under Labour and Conservative Governments (as opposed to the myths).

With the exception of The Labour Government 1974-79, Tory Governments (including this one) have since 1965 spent more while in power than Labour ones. Even under Thatcher and Major.

The real question is did Labour spend too little in the last government?
