As I mentioned earlier, commercials are buying GBP, and I'd expect quite a few more did so yesterday.
Doesn't mean that they expect the fall to stop, they have no specific opinion on that.
Analysts' opinions are divided, the Boe will act if a fall against Usd continues (likely a statement on int rates), if a new base forms at current levels then no immediate Boe statement needed.
I mentioned back awhile that Eur/Gbp levels around 80.00 are very acceptable to many businesses, so there is no immediate need for action on that front.
The largest problem, right now, is cable - a comparison of the monthly chart on Gbp/Usd and Eur/Gbp gives a sense on the likely direction of consumer prices for the UK.
