That no Argentinian priest shall tithe or toll in our dominions.

If the Falkland Islands dust-up (1982) was 'the last war of the 19th century', the Brits seem to be looking back a little further still;

Pope Francis, who is a former Archbishop of Buenos Aires, has previously described the disputed territory as belonging to “the homeland” of Argentina.

However, the Prime Minister told him he should “respect” the islanders’ referendum vote for the Falklands to remain British.

Mr Cameron even dared to make a joke at the expense of the Vatican’s ancient election processes.

“The white smoke over the Falklands was pretty clear,” he said.
