Briton Simone White has died after a suspected methanol poisoning thought to have killed four others in Laos, south-east Asia.
The lawyer from Orpington, south-east London, was among a number of people taken to hospital following the incident in the tourist town of Vang Vieng.
Earlier, Bianca Jones, 19 from Australia, was confirmed to have died while the US State Department said an American had died. Two Danish women aged 19 and 20 also died last week, Danish authorities said.
In a statement, the Foreign Commonwealth and Development Office (FCDO) said it was supporting her family.
