@BenPennings She wants one nation to win. She doesn't necessarily want to be PM. She wants to be leader of the party. You can be one without being the other. Duh!
@ClareONeilMP During a conveyance, what is done to ensure that a buyer is not foreign? Conveyancers are supposed to check, but when have you ever heard of them being audited? Typically they do not ask for a birth certificate or passport. They just assume the person is not "foreign".
If you want cheaper housing, cut immigration, streamline the building approvals process, release more land, ban foreign land ownership, restrict corporate land ownership to factories and offices, and encourage people to become tradesmen. Reduce the leaving school age to 15 so that those with no ability or interest in academics can learn a trade earlier. Import tradesmen from countries known to excel at them (like Germany) so as to improve the quality of training.
