Under the present arrangements, England have more of Rupert Murdoch's cash than the other three countries put together, with pounds 22.5m earmarked for the clubs over a five-year span."It sounds a great deal of money, but in reality it is barely enough," insisted David Tyler, a leading administrator at Bristol and an Epruc insider."The clubs would be enraged if a single penny of that sum were to be negotiated away by the RFU on Tuesday. If that someone turns out to be Epruc, the English clubs' organisation representing virtually the whole of Courage Leagues One and Two, the threat of a breakaway will be back on the agenda. The Welsh - and by extension the Irish and the Scots - will insist on Tuesday that the Sky monies be shared equally between the home nations. Fears over the re-negotiation of the Rugby Football Union's pounds 87.5m television deal with Sky has left the domestic game teetering on the brink of open warfare little more than a month before the start of the new season. There will be so many power bases to protect and so many vested interests to pursue when talks between the four home unions resume on Tuesday (France have negotiated their own television rights for more than a decade) that whatever agreement is eventually struck, someone is going to feel sorely aggrieved.
