Sure. I will start and I may turn to my colleague Sally to give some more recent examples. Her memory is better than mine.
We don't know what those are for just yet. This is the notion that we come to Parliament for supply through the mains and then the supplementary estimates (A), (B), and (C) typically, but not always.
Sometimes there are cases where a department cannot wait for the next supply period to get funds. So this is a vote we use to actually top up a department until we can get to the next supply period. Then the information is reported to Parliament so they can be aware of what this vote was used for.
Going from memory, it was used last year. I believe it was through supplementary estimate (C). There was an opportunity to amalgamate two buildings we have in London related to our embassy, to consolidate them. It was a time-sensitive deal. The department in question didn't have enough money to actually buy this property and wanted to take advantage of what was, in fact, a very good deal for the taxpayer. So we used this vote to top them up until we could come back to the next supply period.
In the past, it's also been used to fund Indian and Northern Affairs for things such as forest fires when they've had costs they didn't anticipate.
Sally, is there anything else?
