On 22 May, the heads of the U15 and the Russell Group university alliances published an open letter to address the future of international research cooperation between Germany and the UK. They praised the role that international research has played in the current COVID-19 pandemic, and reiterated the commitment of their university alliances to maintaining research ties across Europe. They urged their governments to support future collaboration,
acknowledging the key role that this research will continue to play in rebuilding societies and economies in the wake of this pandemic and post-Brexit.

The letters have been published in the Tagesspiegel and in Times Higher Education.
