LONDON, Jan 31 (Reuters) - Argentina has been given permission to appeal after losing a London lawsuit brought by four hedge funds over euro-denominated securities which left the country facing a roughly $1.5 billion bill, Argentina's lawyers said on Wednesday.

The funds, holding around 48% of the securities linked to Argentina's gross domestic product in 2013, won at trial and a judge ruled Argentina should pay 1.33 billion euros ($1.44 billion) plus interest in relation to all the GDP-linked securities.

But Argentina was given permission to challenge that ruling earlier this month, the country's lawyers said in court filings at a preliminary hearing at the Court of Appeal in London. (Reporting by Sam Tobin; editing by William James)
