We're all curious about it. It probably has to start with the main opposition actually acknowledging that Brexit is harmful. At the moment they've all been ordered to shut up about it.
That range is significantly lower than 16.2%.
where does this rumour keep coming from?
bar during covid I haven't observed this in any supermarket (unless you go at 9pm on a Saturday night or something, where they haven't restocked yet)
Prices are rising for some lines though.
The idea that this is a "global problem" is convenient for the UK government and Brexit supporters, but not based in reality.
I don't know about reality, but what you've done is delivered anecdotes when we know that prices in the US have gone up about 10% and prices in the UK have gone up 15%. There's no need for anecdotes, especially for another round of calling Brexiteers deluded.
Eggs got expensive here but it’s generally been in stock.
