The early departure of Gordon Brown from office is now openly being discussed in Labour circles. Alex Hilton of LabourHome is reporting that a stalking horse candidate plans to challenge Gordon Brown. He doesn't name the MP concerned but I believe it to be Charles Clarke, whose patience has finally snapped. However, he may not need to man the barricades.
A very reputable Labour parliamentary source claims that "Gordon is hating being Prime Minister." He certainly wouldn't be the first PM to get the job only to find out that he didn't really like it. Harold Macmillan would fall into that category.
Labour MPs are increasingly coming to believe that if the European elections are terrible, Brown may well decide he's had enough and quit while he's, er, behind. I suspect this is a case of wishful thinking on their part, but who knows?
