If I could perhaps give one example, standing orders are only permanent until they're not, once it's not written into tablets of stone that standing orders can never change.
I think of a previous experience of a completely different crisis, for example the expenses crisis that we had a few years ago in Westminster. A lot of things were changed as a result of that crisis. Some of those, I think, perhaps were regretted afterwards, but others were not.
Short-term changes can be short term, can be limited, but they will still stick in people's minds as a memory of the thing that happened that was good or bad or indifferent. It will alter people's views of how Parliament should work, having had it work in a slightly different way for a while.
