Murdered student is named by police.
The student was reportedly found with a deep cut to her throat in her bedroom in the town of Perugia.
A Foreign Office spokesman said: "The circumstances of the death are under investigation by the Italian police."
Her partially clothed body was discovered under a duvet early yesterday afternoon at a house in the Viale Sant'Antonio, not far from the town centre.
Police found the body when they went to return a mobile phone discovered in a nearby garden.
Miss Kercher had been in Italy since August as part of a university exchange.
Police said the door seemed to have been locked from the inside and officers were concentrating on a bloodstained window.
