Tutu turns 75

Nobel peace laureate Desmond Tutu turns 75 tomorrow – his acerbic tongue and irrepressible humour as sharp as during his anti-apartheid crusades.

Some 1,200 guests – including former President Nelson Mandela – are due to attend a gala dinner in Johannesburg, capping weeks of celebrations in honour of the retired archbishop of Cape Town, or Arch as he is fondly called.
