Behind the scenes
This Prime Minister was left unnamed as The Dying Days was being written just before the in the real world. Lance Parkin reminisced about this in the 2003 ebook release of the novel:

"As Benny notes in chapter one, I couldn’t pin down the name of the President of the United States or the Prime Minister, because there was going to be an election in both countries between me finishing the book and its publication. The Tories should have bribed me to say the PM was Tony Blair, simply because sod’s law would almost certainly have guaranteed a landslide for John Major. But they didn’t, and the rest is history. One of the amusing things, though, was that Staines could comfortably be either a Conservative or a New Labour Home Secretary."
