A resolution, of sorts, seems to have been found, as is being reported today. Beamish and Fosters will be on sale in their Irish bars, but not Heineken or Murphy's, presumably due to brand positioning, the latter being "premium". I think it's business as usual again in the UK.
Also a couple of vintners (e.g. Charlie Chalke) confirmed over the last few weeks they "had made representations" to Heineken about Wetherspoons.
