The pound hasn't been devalued recently. It simply finds it's own level relative to other currencies based on dealers confidence in sterling. Low confidence leads to a fall in value. Under current legislation the government has no power to devalue the pound. The current government's wish to encourage export is one it has little control over. It can hope banks lend to companies at low rates by hoping the bank of England keep bae rates low, but it has no control over either of those outcomes. It can send envoys out to other countries to 'big up' our products, but since Prince Andrew (I kid you not) is currently in the job, I can't see that helping. It can sell goverment debt, which might have some negative effect on sterling, but only if lots of our competitors aren't in the same debt ridden boat (which they are). In effect, this govenments wish to boost exports is just that - a wish - It has virtually no method of ensuring that it happens...
