The UK's Premier League football competition has become mired in controversy over the past week as a result of the Rainbow Laces campaign.

Rainbow Laces was launched by Stonewall, a UK-based LGBT rights charity, with athletes and fans being encouraged to wear rainbow-coloured laces.

Following previous successes of the campaign, the Premier League now collaborates with Stonewall on the Rainbow Laces campaign every season. The Rainbow Laces Week typically takes place each year in November or December.
