Mordechai Vanunu seeks permission to leave Israel

Here's a piece by Duncan Campbell in The Guardian on the treatment of nuclear whistle blower, Mordechai Vanunu, by the Israeli authorities:

Britain has a responsibility towards Vanunu, a man who gave his story to a British newspaper – the Sunday Times – and whose kidnap and removal from Italy started on the streets of London; Israel had not wanted to embarrass Margaret Thatcher's government by carrying out the deed in the UK. It is time that the British government recognised the British link and spoke up for a man who risked his freedom and his sanity because of his hatred of nuclear weapons. And high time that a peaceful man in a violent world was allowed to live his own life in peace.

I have always wondered why the successive UK governments have been so cavalier about a kidnap that was initiated in London.
