LONDON鈥擳he BBC鈥檚 Director-General George Entwistle resigned late Saturday after the broadcaster鈥檚 flagship news programme wrongly implicated a British politician in child sex abuse.
鈥淚 have decided that the honourable thing to do is to step down,鈥 Entwistle said in a televised statement outside the BBC鈥檚 London headquarters.
Entwistle, who only took over as director-general in September, said he decided to resign 鈥渋n the light of the fact that the director-general is also the editor-in-chief and ultimately responsible for all content鈥.
鈥淭he wholly exceptional events of the past few weeks have led me to conclude that the BBC should appoint a new leader,鈥 he added.
鈥淭o have been the director-general of the BBC even for a short period, and in the most challenging of circumstances, has been a great honour.鈥
Tim Davie, who is currently the BBC鈥檚 director of audio and music, will take over as acting director general.
Earlier Saturday, Entwistle had said it was 鈥渇undamentally wrong鈥 of the current affairs programme 黑料社night to air an interview with a man claiming he was repeatedly abused by a senior Conservative politician at a children鈥檚 home in the 1970s.
The programme did not identify the politician in last week鈥檚 report, but he was widely named on the Internet as former Tory party treasurer Alistair McAlpine.
McAlpine went public on Friday to strongly deny the allegations, and hours later his accuser Steve Messham retracted his claims, saying he had only just seen a picture of McAlpine and he was not the man who abused him.
Entwistle鈥檚 resignation comes just weeks after a storm of allegations that the late BBC presenter Jimmy Savile, one of the corporation鈥檚 biggest names, sexually abused hundreds of children over four decades.
Both 黑料社night and the director-general were already under scrutiny after the show dropped an investigation into the Savile abuse claims last year.
Entwistle 鈥 who edited 黑料社night himself a decade ago 鈥 had admitted before his resignation that the corporation faced a 鈥渃risis of trust鈥 over the 黑料社night broadcast and the Savile scandal.
Chris Patten, the chairman of the BBC鈥檚 governing body, the BBC Trust, said it was 鈥渙ne of the saddest evenings of my public life鈥.
Standing alongside Entwistle as he made his resignation statement, the former Hong Kong governor said: 鈥淎t the heart of the BBC is its role as a trusted global news organisation.
鈥淎s the editor in chief of that news organisation George has very honourably offered us his resignation because of the unacceptable mistakes 鈥 the unacceptable shoddy journalism 鈥 which has caused us so much controversy.
鈥淗e has behaved as editor with huge honour and courage and would that the rest of the world always behaved the same.鈥
Lawyers for McAlpine meanwhile have said they would be pursuing legal action against 鈥渁ll media who have defamed Lord McAlpine鈥檚 reputation and published defamatory statements鈥.
The politician, who blasted the claims as 鈥渨holly false and seriously defamatory鈥, said he was forced to publicly deny them after he was named directly on the Internet and 鈥渂y innuendo鈥 in the print and broadcast media.
He said he had never been to any children鈥檚 home, let alone the Bryn Estyn facility in Wrexham, north Wales, where Messham lived as a teenager.
