She said the government had taken steps to reassure EU citizens in Britain that there would not be any immediate changes to their circumstances following last month's vote to leave the bloc.
"Clearly we are then going to enter a process of negotiation with our other EU partners about leaving the European Union and there are a whole range of complex issues including this one which will need to be worked out," she told reporters.
"The decision will be for the next prime minister and part of the discussions about how the UK leaves the European Union and what relationship we have with them in the future."
