The United Conservative Party has released a statement that Innisfail-Sylvan Lake MLA Don MacIntyre has resigned from caucus.
UCP leader Jason Kenney's statement says MacIntyre resigned at about noon.
MacIntyre published a Tweet this afternoon saying he was resigning from politics to focus on family.
It was unclear if he had resigned as an MLA as well.
Earlier today, party leader Jason Kenney issued a statement saying MLA Derek Fildebrandt would not be permitted to return to caucus, and that those seeking a party nomination would be screened for any outstanding legal or ethical issues.
