The Home Office has the reputation of being something analogous to the tar-pit of the Civil Service, where the terminally thick are sent to languish until retirement if they cannot be sacked. Thus we have this repeated series of attempts to make the laws of humans triumph over the laws of physics and mathematics.
Once more the same points will have to be made: strong encryption methods exist already in the wild and people know what they are and how to use time. Unbreakable encryption such as one-time pads also exist, and people know that these are unbreakable if used correctly (and thanks to innumerable Cold War spy dramas, everybody knows how to use one-time pads; the clue is in the name).
So, if you try to insert holes into encryption products, people will simply layer more encryption over the top of the leaky product and defeat you.
