Even if S2/28 runs when the World Cup is on, the BBC has scheduled the following matches:
Saturday 10 June - England match at 2pm only
Saturday 17 June - Portugal v Iran at 2pm only
Saturday 24 June - one match only starting at 4pm or at 8pm. If England are playing it will be on BBC at 4pm.
Saturday 1 July - one match only starting at 4pm or at 8pm. If England are playing it will be on BBC at 4pm. BUT a possible clash with a British tennis player in the third round at Wimbledon.
Saturday 8 July - Third Place play off at 8pm if BBC show it.
15th April ties with starting at the Easter weekend again PLUS the weekend of the 8-9 July would see the end of series 2/28, the World Cup Final and the Wimbledon finals.
Wimbledon & World Cup may result in a change of time, like it probably will on 20th May 2006 for the Eurovision Song Contest, just as 'The Empty Child' was brought forward to accomodate Eurovision 2005. If Doctor Who is on at 7pm, there still would need to be a lottery programme before any other sport programme / Eurovision etc.
Disappointing to wait til then BUT it'll be worth the wait!
