The pound has fallen below US$1.29 for the first time in almost a year on continuing worries Britain will leave the EU without a trade deal. Sterling also hit a nine-month low against the euro, and was down against the yen and Swiss franc.
The pound has continued its recent strong run against the dollar pushing firmly above US$ 1.43. It is the seventh session in a row that the pound has made gains against the US currency. The strong run means that, among the G10 group of rich nations, the UK has the best-performing currency this year.
The British pound has fallen against the dollar to below US$1.20 ahead of a key speech from Theresa May on Brexit this week. Sterling fell 1.5% against the US currency on Sunday to its lowest level since the flash crash in October.
