[Question] What’s the effective R for the Delta variant of COVID-19?

I have the impression that R for COVID-19 overall matters at the moment relatively little. What’s matters is the R for the Delta variant. When Googling I can’t find any such data for the US, the UK or any European state. I’m not sure whether this is due to incompetence or malice of authorities, but anyway, does someone have a good source or did the analysis themselves?

(extra points for the R of Delta plus which does have another spike protein mutation and thus vaccine antibodies are going to bind less well)
