Love the BBC with their unbiased reporting, “look how many rich pensioners there are now  compared to 2010”.

Hmmm, let us consider the value of that £1 million in 2010 compared to today. Taking official cpi figures, £1 million today would be worth £683207 in 2010, but based on actual inflation I would say closer to £400k.

So in fact I’d say there are likely slightly more with around £1.5m reported cpi but probably less than 9% with around £2.75m actual inflation adjusted “millionaires”
