Look at your website. That is not what it says. Your website says, item three, “Have either obtained four percent of the vote in a previous election”—this is your website—“or a legitimate chance to win seats in the upcoming election”. Criteria number one is the one that refers to having “a Member of Parliament elected...in the House of Commons at the time the election is called”. This is your website, so what you just quoted to us is not what your website says.
