Not all that surprising, typical Conservative double-speak (or is it talking out of both sides of their mouth?).

We had something similar here in Australia in the early 2000s, when we voted on a referendum on whether to ditch the Monarchy and become a Republic:

All of the Stay/Remain advertising focused on the message that “this [proposed] Australia’s Not The One”, and inferring that we could have another referendum in the near future with a different form of revised Government. Suffice to say, that was utter bullshit - and we haven’t revisited the topic since.

By then again, we wouldn’t even pass a referendum to allow the Aborigines a Voice in Parliament a few years ago - so we’ve probably rolled backwards also.
