A parliamentary petition to stop all immigration and close the U.K. borders until ISIS is defeated is now at 450,000 signatures and growing.

Allowing uncontrolled immigration and taking in these refugees potentially endangers the entire UK population. At any other time in our history this would be tantamount to a declaration of war and borders would be closed.

The British Home Office has already responded to the petition, stating that “[t]he UK government has no intention of closing Britain’s borders, as this would create more problems than it would solve.”

Comparing the map for supporters of the call to close the U.K. borders and halt all immigration with the corresponding map for supporters of the petition to ban Donald Trump from the U.K. clearly shows that the former has widespread support in urban and rural regions of the United Kingdom, whereas the latter is concentrated on highly urbanized areas such as Greater London.

One must also question whether the petition to “Block Donald J Trump from UK entry” has been fraudulently manipulated by non-UK sources.

The raw data files behind these two petitions can be downloaded directly from the parliamentary petitions website. In these files, the “Block Donald J Trump from UK entry” petition has—at the time of writing—a total signature count of 527,669, but the data file lists only 253,966 signatures coming from the U.K. itself. By comparison, the “Stop all immigration and close the UK borders until ISIS is defeated” petition has a total signature count of 449,285, of which the U.K. signature count is 439,483.

In other words, according to the U.K. parliamentary data files on these two petitions, it appears that only 48 percent of the signatories for the petition to ban Trump came from within the U.K., whereas 98 percent of the signatures for the petition to close the U.K. border and halt immigration are sourced from within the U.K.
