BBC Sport outlines the promotion and relegation issues - and European qualifiers - in England and Scotland.

Bury became the first Football League team to be relegated after losing 1-0 to Oldham on 13 April, while Hartlepool United and Portsmouth were both condemned to League Two without kicking a ball when Oldham beat Yeovil 1-0 three days later.
Pompey were effectively down anyway as they knew they would be deducted 10 points when they came out of administration, which they did on 19 April, while the last relegation place went to Scunthorpe United who, despite a 3-1 win over Swindon on the final day, finished three points from safety after Colchester won 2-0 at Carlisle.
