That brings me to my final question. It might not be in Mr. Johnson's wheelhouse, but I am trying to get a sense of what aspects of indexation are British Government policy and which are set down in legislation. My assumption is that, while elements like the triple lock are legislative and binding, we have established that much of indexation can be largely set aside or varied at the behest of the Government.

I am aware that Mr. Johnson is not a legislator, but in the context of his understanding of the matter, how much of indexation is policy and how much is legislative?
