evidence: The Northern Ireland Executive has pledged to pay £62.5m, the Irish government has promised €50m (£43m) and the GAA - the sporting body which oversees Gaelic games - has said it would contribute £15m. [...] At that time, Northern Ireland's three main stadiums for football, rugby and GAA - Windsor Park, Ravenhill, and Casement - were seen as increasingly not fit for purpose. [...] Most football league grounds in Northern Ireland are in dire need of redevelopment. And with the £25m earmarked for Windsor, it would mean football and Gaelic games both getting an equal slice - £61m - from the public purse.
