Excerpt:
West Midlands MP Bill Etheridge has warned he will resign from UKIP if an anti-Islam candidate backed by Tommy Robinson becomes leader.
Anne Marie Waters, founder of the "Sharia Watch" pressure group, launched her leadership bid in Rotherham over the weekend.
She has described Islam as "evil" and a "killing machine", and founded anti-Islam pressure group Pegida UK alongside ex-ELD leader Tommy Robinson.
And UKIP MEPs are reported to be concerned that the party has been infiltrated by far-right activists hoping to make Ms Waters leader, after a large number of new members joined.
