Kanye West’s expletive-ridden performance at Glastonbury 2015 has prompted TV viewers to complain to Ofcom.

The rapper headlined the festival’s Pyramid Stage on Saturday night and prior to the performance, the BBC told viewers to “expect bad language”, revealing that they had “contingency plans” set in place. They also aired a warning prior to the broadcast.

The BBC decided not to censor any expletives used during the performance, but screenshots of the subtitles went viral as fans noticed the lyrics had been changed to avoid replicating the bad language and use of the N-word.

Ofcom said it received 44 complaints about offensive language during Kanye’s set. It is assessing the complaints before deciding whether to investigate.

The figure is less than the 151 complaints Ofcom received about the Brit Awards and the rapper’s use of the N-word just after the 9pm watershed in February this year.

Meanwhile, the major clean-up operation to turn the 1,000 acre setting of the Glastonbury Festival back into a farm has started.

The final campers are preparing to leave after the festival was closed last night by 60s rock and roll band The Who.

Debris left by 135,000 ticket-holders is strewn across the fields of Worthy Farm in Somerset, which has been home to a population bigger than Oxford and Reading for the past five days.

Around 800 litter-pickers will begin the pain-staking task of collecting the rubbish before the stages are packed away for another year as bleary-eyed campers begin a congested journey off the farm and home.

Co-organiser Emily Eavis described the festival – which has been particularly diverse and controversial this year with a last-minute cancellation from the Foo Fighters, a stage invasion during Kanye’s headline performance and a visit from Tibetan spiritual leader the Dalai Lama – as the best yet.

Meanwhile Avon and Somerset Police said it recorded one of the lowest crime figures it has seen in recent years, with 216 crimes reported compared to 246 last year.

A spokesman said 75 arrests had been made, mainly for thefts from tents and drugs offences.

The weather was just as extreme as the performances this year, regularly switching from sunshine to downpours but campers were grateful to have dry weather today as they packed up their tents.

Ambulance staff said the muddy fields were responsible for causing dislocations and fractures as campers battled through the slippery fields and pathways while others suffered from heat stroke and burns.
