Where did I say Invictus doesn't matter?
If one service in a run up of 3 years to the next games is the game changer for the event not coming to the UK, then it's not much of a bid on the part of Birmingham and the MPs involved, and the committee isn't particularly sensible, is it, given Birmingham ticks every single box one could possibly want ticking for putting on a sporting tournament. Why do you think that's more damaging and would sway the committee against Birmingham than, say, the slaughter of thousands of Christians in Nigeria and their disgusting attitude to homosexuality?
Why would the committee making the decision think their event is so poor that it could be overshadowed by the a non-presence of other royals, when the main royal involved, Harry, will be there, and presumably his wife too? Unless her current "boycott" of the UK continues, which I would have thought would be more damaging.
