Travellers can expect to see their cash stretch further on trips abroad following Brexit.
More than three quarters (80%) of the top 40 holiday currencies have fallen in value against the pound compared with a year ago and all are weaker than last summer, according to Post Office Travel Money.
This means that Britons travelling abroad will get up to 22% more for their pounds than a year ago.

Holiday costs fall as sterling strengthens and prices drop
All-inclusive holiday seaches ‘soaring in peaks’
Nick Boden, head of Post Office Travel Money, said: “Sterling is now stronger against the vast majority of holiday currencies and that spells great news for holidaymakers.
“UK tourists can do even better by picking a destination where the cost of living is low so they benefit from both the stronger pound and low prices in resort restaurants and shops.
“However, sterling is entering uncharted territory and exchange rates could continue to fluctuate throughout 2020 as trade negotiations with the EU progress.
“We advise holidaymakers planning trips abroad in 2020 to keep a close eye on rate movements and purchase foreign currency when sterling will give them more cash for their pounds.
“Budget realistically to avoid running out of holiday cash and having to use credit or debit cards abroad, which are likely to incur extra fees.”
People visiting Turkey will get the best value because sterling is worth 19% more against the Turkish lira than a year ago. Tourists buying currency now will get around £80 more in lira on a £500 transaction.
Other destinations where the strength of sterling will benefit include Chile, Brazil, South Africa, Norway and Mauritius.
