Sterling slid to a nine-month low against the euro on Wednesday as investors sold the currency fearing Britain could soon leave the European Union without securing a trade deal.
Sterling has slumped recently due to traders hedging against what they see as the growing chances of the currency plummeting if Britain crashes out of Europe in less than eight months' time.
The pound sank to an 11-month low versus the dollar on Monday after Britain's trade minister Liam Fox suggested the UK could leave the EU in March without an agreement to ensure future relations with the bloc, its biggest trading partner.
"A lot of companies can't wait for the negotiations outcome in October so a lot of course are trying to hedge against drop in the pound," said Christophe Barraud, an economist at Market Securities brokerage in Paris.
Sharp rises in the euro and the dollar recently have exacerbated the pound's woes.
Sterling fell 0.2% to as low as 89.84 pence , its weakest since the middle of November.
The pound also slipped to a fresh 11-month low against the dollar of $1.2912, falling below Monday's low of $1.2920.
British Prime Minister Theresa May will meet with fellow EU leaders in October to try to seal deals on the terms of Britain's withdrawal.
"We remain bearish on the pound in the short term until the Brexit mess is out the way and look for the currency to enter a $1.27-1.28 range before the leaders summit," said Nomura strategist Jordan Rochester.
The pound has fallen more than 10% since mid-April, and with the government yet to agree a divorce deal with Brussels, currency traders are growing edgy about its outlook.
