Portcullis Public Affairs
London-based PR and lobbying consultancy set up by chairman Charles Cockburn in 1989.
Portcullis chairman Charles Cockburn presented a positive spin on the loss, telling Public Affairs News about the results his agency had achieved for Ineos in recent years:
- On one of our recent projects for Ineos we delivered a return on their investment of more than 12,000% and this comes hard on the heels of helping our client secure Grangemouth’s future late last year.
- We note last Thursday’s announcement by Chief Secretary to the Treasury, Danny Alexander, that INEOS would benefit from a loan guarantee of £230 million to underpin the investment in the Grangemouth plant to enable it to store and process shale gas shipped in from the US. We are proud of the part we have played in producing this excellent result, which will secure jobs in Scotland while benefiting the wider UK chemicals industry."
- Cockburn added: "Ineos has now moved on, after three years, as we have delivered the goods. We are delighted that our advice on Grangemouth produced such a brilliant result."
