Billboards advertising a nasal spray to help with impotence which were removed from Edgware after protests that they were offensive are being taken down in the rest of the country.

Orthodox Jewish councillor Brian Gordon was among objectors to the posters headlined “Want Longer Lasting Sex?”

The Advertising Standards Authority is considering more than a hundred complaints about the adverts.

But the Australia-based Advanced Medical Institute said it had ordered billboards for its product to be taken down before the ASA decision.

The company said: “Due to the unprecedented level of complaints and negative media coverage... and because our focus is on helping men with premature ejaculation and erectile disfunction, and not on public rows with the ASA, we have instructed that the billboards be removed as soon as possible.”
