Retired Anglican Archbishop Desmond Tutu and his wife Leah have renewed their wedding vows to celebrate 60 years since they married.

A Eucharist service was held at St. George's Cathedral in Cape Town on July 2, and another will take place at the Holy Cross Anglican Church in Soweto' on July 4.

Nobel Peace Prize laureate Tutu has often paid tribute to his wife' both sincerely and with humour' for the support she gave him while bringing up their children during the anti-apartheid struggle where they endured political pressures.

He credits her for ensuring humility in him.

"Leah has been very good at keeping my head the right size'" he told Times Media in an interview.

"Once I was driving and when I looked at her she looked slightly more complacent and self-satisfied than usual.

"When I wondered why' she showed me this bumper sticker that said' 'Any woman who wants to be equal to a man has no ambition'.

"The other day she stuck a notice just beneath the television set in our bedroom that said' 'You are entitled to your wrong opinion'."

Leah Tutu' when asked the secret to staying in love over many decades in 2011' said: "There is no magic to making marriage work. A marriage is never made in heaven' you make it what it is. If you love a person' it's simply not enough. You must meet halfway' give and take' for the rest of your lives".

She recalled she met "the Arch" as he is commonly referred to know when he was a stubborn headmaster's son who ignored her as a young girl' and whom she "chased" in their college years.

She told South Africa's The Times newspaper: "I still think he's very good looking".

"We greet each other every morning and night with a kiss."
