Following are comments from advertisers, many responding to a barrage of messages on Twitter from consumers, politicians and celebrities calling for boycotts of News of the World and other UK titles belonging to Rupert Murdoch including The Sun and The Times.
Bourne Leisure (Butlins, Haven Holidays, Warner Leisure) - "We review all our sources of advertising regularly and we will not be advertising in NoW (News of the World)."
Coca-Cola - "We have no advertising currently running with the News of the World and none scheduled for the future. We are shocked by the new allegations that have been made."
The Co-operative Group - "The Co-operative Group has taken the decision to suspend temporarily any further advertising and promotional activity with the News of the World until the outcome of the investigation is known. The Group is a consumer-owned business which adheres to strong ethical standards. These allegations have been met with revulsion by the vast majority of members who have contacted us."
Dixons (Currys and PC World): "There are a number of factors that determine our media planning and we constantly review all the media we use. However, we do not comment on specific cases."
EasyJet - "EasyJet understands the concerns raised by the public, including many of our own staff and passengers, about these serious and shocking claims. We will actively monitor the situation and await the outcome of any investigation."
Ford - "We are awaiting an outcome from the News of the World investigation and expect a speedy and decisive response. Pending this response we will be using alternative media within and outside News International Group instead of placing Ford advertising in the News of the World."
