PSC Patron, Alexei Sayle, had the following letter published in the Guardian:

In last Saturday's Guardian (26th November 2011) there was an advert for travel to Israel featuring a map where Israel appears to have absorbed the entire occupied Palestinian territories and the Golan Heights. The Israeli Board of Tourism has been censured three times for breaches of advertising standards, but seems unable to correct its behaviour. Perhaps you should now just refuse to offer any advertising space to the Israeli government, which repeatedly claims that land illegally acquired by conquest is theirs.

The Guardian has confirmed that it has refused to publish the follow-up adverts following complaints

The Advertising Standards Authority have received so many complaints that they warn visitors to their website that they will not respond to further complaints on this issue. However, they add that "receiving complaints will provide us with an opportunity to continue to monitor public response to this ad".
