Dr Sentamu cut up his collar in protest over Robert Mugabe
The Archbishop of York, Dr John Sentamu, has called on South Africa to take action over Robert Mugabe's regime in Zimbabwe.
Dr Sentamu cut up his dog collar in protest against the regime last year.
On Sunday he issued a plea to the South African president, Thabo Mbeki, to intervene directly.
The Archbishop said South Africa should remember global pressure forced a change in the system which had previously governed their lives.
Speaking outside York Minster, Dr Sentamu said: "It is not too late for you [South African government] to liberate yourself from the suggestion that because Mugabe was a war veteran, we can only just simply persuade him.
"You know, in Uganda we were liberated by Tanzania saying enough is enough.
"South Africa, please, for Heaven's sake, stop all this suggesting that this is going to be imperialism, this is going to militarism.
"Remember a lot of people in the West put pressure on the then apartheid government - and that apartheid government had to bend to the will of the international community.
"So South Africa, for Heaven's sake just wake up to what is happening in Zimbabwe and your own country, you've got four million refugees which you can ill afford."
