This figure is exchange rate dependent. Although the 'current' figure would be around £83.5k at the older rate it would have been £62.5k.
In the future the exchange rate could exceed €2 to the £ which would leave savers worse off. You could argue that such a link is a little like oil being sold in US$ and the exchange effect on the price of fuel here. Is it not better to have a 'safety net' linked solely to our £ rather than something else?
