First published on: 12th March 2020

It is with a profound sense of regret that the USPG Senior Management Group has taken the decision to cancel the forthcoming Rethinking Mission Conference.

This decision has been taken as a direct result of the uncertainty surrounding the spread of the corona virus.

We are grateful to everyone who booked a place at the conference and hope that we will be able to welcome you to a future event.

Alternatively, if you would like your £10 to be donated to the USPG 2020 Lent Appeal, do not contact USPG and the monies will be transferred to the Lent Appeal automatically. This will be done if we have not received instructions from you by 1700 on Friday 27 March 2020.

USPG regrets any inconvenience caused to you and looks forward to welcoming you to a future USPG event.
