Sorry, I didn’t mean to imply this, and don’t expect Monzo to publish purchase values. I meant to say the local authority approach is one sort of transparency.
Yes of course, but some suppliers are certainly not based in the UK, nor pay corporation tax in the UK. The payment services provider with problems seems to be in United Arab Emirates, AWS is owned by Amazon Inc, and MasterCard is also in the US. I’d simply like a list of who they are and where they are based. Using a supplier is investing in them as well, both in terms of money, and in trust.
