Economists believe the dollar could fall further
The pound was worth $1.9736 in late New York trade on Tuesday - up from $1.9613 when last traded on Friday, as the dollar's recent weakness continued.
The dollar also slipped against the euro and the yen, although trading was thin on US markets.
Economic concerns saw the dollar fall 14% against the pound last year.
