The British Football League is a proposed association football league which would involve the merger of the Scottish, Welsh and possibly the Northern Irish football league systems into the larger English football league system.

When the English Football League was originally founded it was intended to be a UK-wide league, hence the involvement of some non-English teams in the system. However, after the set-up of the independent Welsh, Scottish and Northern Irish league systems teams located within those nations were encouraged to play within that nation's league system.

Supporters for the proposal include many chairmen of Scottish and Welsh teams, as well as some English club chairmen. However, FIFA president Sepp Blatter is opposed to such a move.

Arguments for

• The smaller Welsh, Scottish and Northern Irish league systems are not financially viable as independent bodies.
• Several clubs, such as Cardiff City, already play in the English league despite being located outside the English border.
• Several other nations have a joint league system, such as New Zealand and Australia, or Switzerland and Lichtenstein.
• The English league system was originally meant to be a British-wide system.
• The UK is the only country to have multiple 'national' leagues.

Arguments against

• Each nation has its own national side, and so should have its own league system.
• If clubs were to join the English system, they may have to start from the bottom of the league system.
• The proposal is motivated by purely financial reasons.
• If successful, many other nations may demand to merge with their neighbours.

Alternative proposals

• A 'British Cup', that is a domestic cup competition involving teams from all league systems.
• A very small number of clubs, probably just the two Glasgow 'Old Firm' clubs, Celtic and Rangers would join the English league and the rest would remain where they are.
