Well, now that you've mentioned it, Johnson is preparing a National Government ID project to tie all different services together and bridge these various ID number issues.
It will be a grand, sweeping project with an initial budget of just £80 million, to be completed in three years. Three years after that, costs will have ballooned to £450 million, and the planned end date will be six years from then. After ten years working on the project, UK Gov will sadly conclude that £935 million were wasted and bin the project.
