Well l can only speak for certain about my own town Tamworth in Staffordshire. We have a group called Tamworth Covenanting Churches, TCC . I recently became my churches rep on TCC . The group is made up of all the local churches , Anglican, Catholic, Baptist etc . We often pool resources and people for joint ventures, though obviously public events have stopped lately.
I believe that a lot of towns and cities have similar groups. So some unity is being achieved here in Blighty anyway .
