Putting the modern Treasury into 1930s Britain

Would the modern British Treasury help the Axis if its organization and powers were transported to the 1930s?

The modern institution would struggle to survive because interwar ministers would reject its current degree of control over departmental spending.

The central question is whether the modern Treasury could function within 1930s political norms. Once Parliament and cabinet approved a department's budget, senior ministers would have resisted later Treasury intervention far more aggressively than their modern counterparts. A few hundred interwar staff compared with several thousand today also illustrates the expansion of central financial oversight.
