All I can see in #700 is
@Nikynoo wondering where the £25K debt is from.
You referred to "(T)he £25k parking/LEZ fines debt". If she has that amount being demanded from her for parking or LEZ violations, that would be extremely odd and given she is not a diplomat enjoying immunity from prosecution I agree it would require some kind of explanation.
A £204 demand indicates hardly anything. Many people come back home after a few weeks away and find one of those on their doormats in respect of an alleged violation involving their car. Some unfamiliar 30mph areas, for example, aren't easy to spot until you have already entered them. I'm not defending breaking speed limits, but this kind of thing isn't rare.
Has someone got a link to a readable source (i.e. not video or podcast) for £25K debt whether for parking or LEZ fines or something else?
If she has £25K of personal debt to moneylenders, that's considerably less than average for a British person in these tough times in which we live. Many native Brits are also in debt who don't need to be, or who think student debt, or debt secured on a house, or debt they pay off every month, or debt they're not behind with their payments on, or money they borrow on their credit card to buy food with, isn't real debt. They include some rich educated people.
