England is to make a solo bid to host the 2015 Rugby World Cup.
England's proposal is supported by Prime Minister Gordon Brown and sports minister Andy Burnham after high-level talks at Downing Street.
Scotland, Wales and Ireland are keen on staging the tournament but none of them have the facilities to do it alone.
RFU chairman Martyn Thomas says they'll consider moving some matches to stadiums in the other three home nations.
Cardiff's Millennium Stadium, which hosted games in the 1999 and 2007 World Cups, Murrayfield in Edinburgh, Hampden Park in Glasgow and Croke Park and Lansdowne Road in Dublin are obvious candidates.
