The Reform UK broadcast can be seen on Facebook and YouTube. Contributors will include the usual Reform suspects such as Tice and Bull - Tice is planning to broadcast from a helicopter flying overhead - plus TalkRadio's Julia Hartley-Brewer and Reclaim's Calvin Robinson and Martin Daubney. We assume Daubney is now with Reclaim, seeing as he is seldom seen more than a few feet from Laurence Fox these days.
Telegraph cartoonist Bob Moran will also be among the thousands of marchers on Saturday. He is currently on an extended break from the newspaper, although it is not clear whether this has been forced upon him or whether he will return. Judging from his most recent art it's clear to see that he is not going down without a fight.
You can follow Bob on Twitter.
