I’M not impressed by Julia Breen’s weeping and wailing about the initial disruption that would be caused by a no deal Brexit (Echo, Aug 29).

Clearly there will initially be disruption.

But much the most important point is the overall ultimate effect on national output (ie GDP), and hence living standards.

The Bank of England’s latest “worst case scenario” estimate is a 5.5 per cent fall in GDP.

On that basis, the most likely effect may be something like three per cent or four per cent.

I’m not losing nights of sleep over that.
