Maria Voce (Emmaus, to use the name given to her by Chiara Lubich) is the President of Focolare. She works closely with the movements Co-president Fr Giancarlo Faletti. They are undertaking a visit to Great Britain, their first. The details of their visit can be found here.
The Focolare website has a short account of the history of the movement in the UK, to accompany this visit. I expect that reports of the events during the visit will be posted in due course.
