of Scotland Football League, South of Scotland Football League and the West of Scotland Football League. Two English clubs, Berwick Rangers and Tweedmouth Rangers, play in the Scottish system. Outside of the pyramid is one senior league, the North Caledonian Football League, Junior football and amateur football. The Welsh football league system includes the Cymru Premier (historically the Welsh Premier League) at the top level, the Cymru North and Cymru South at tier two, and a number of more regional leagues below these. Premiership club The New Saints began playing their home matches on the English side of the border in Oswestry in 2007. Historically, the Saints represented the small Welsh village of Llansantffraid-ym-Mechain, but merged with Oswestry Town, which had historically played in the Welsh football system, in 2003. Cup competitions There is a multitude of knockout club cup competitions. Again, these are organised on an English, Scottish, Welsh or Northern Irish basis. Many carry qualification for the UEFA Europa League for the winners. Each football association runs its own national cup, the FA Cup in England, the Scottish Cup in Scotland, the Welsh Cup in Wales and the Irish Cup in Northern Ireland. Traditionally, these cups have been the most liberal about whom they accept, with many teams from outside that nation (and/or league system) entering. More recently, rules have been tightened, with the competitions only open to teams who play in that nation's football league system. There are also a number of other cups that have more stringent requirements but carry less prestige, including the Football League Cup in England, the Scottish League Cup in Scotland, Welsh Premier League Cup in Wales and Irish League Cup in Northern Ireland. Some past cups have even crossed UK boundaries, such as the Anglo-Scottish Cup. Another cup competition that crosses the UK's border is the current Champions Cup, which features the champions of the Northern Ireland league and the Republic's. Clubs playing in other countries The nature of the governance of the game in the United Kingdom, with four separate associations, has led to the anomaly of clubs based in one of the four nations playing in competitions run by another. At present, this encompasses the following clubs playing senior football: → - Berwick Rangers, Tweedmouth Rangers → - The New Saints → - Cardiff City, Merthyr Town, Newport County, Swansea City, Wrexham → - Derry City Berwick Rangers, The
