BTW, you can divide the number of Officers by 3 or 4 when talking about 24x7 environments across the country (because it is posts, not individual Officers, that counts). And I would've thought that HMRC staffing should also be upped, along with prioritization of processing Dover declarations at the Salford NCH (National Clearance Hub); better, in fact, that the NCH function is delegated back to the regions.
