The MRC supports preprints - News - Medical Research Council

"The MRC requires that the results of the research it funds are published, ideally in peer-reviewed journals; also that all such articles, whether published in an open access or subscription-based journal, must be archived in Europe PubMed Central (Europe PMC) and made freely available as soon as possible, and in any event within six months of the first on‐line publication.

However, we are now also actively encouraging researchers to share their pre-peer reviewed manuscripts via established preprint servers."
