Rumours in the far right media that Johnson, Gove and Rees-Smog are plotting to overthrow the current Tory leadership. Certainly the far right of the party has been most vocal when Brexit negotiations haven't gone their way.

Would May have much to lose by threatening a general election as a counter to this attack on her premiership? On a personal level, probably not. If she was to lose a general election, she'd probably leave politics. If she was ousted, she'd probably leave politics as well and the DUP deal would collapse, leaving a more right wing Tory minority to eventually collapse.

Should she call a general election she would remain leader and would pitch her idea of Brexit and Conservativism to the country. If she wins, the far right are squashed. If she loses, the far right are a small group in opposition.

I reckon she should consider her own strength as leader and call one. She'd have nothing to lose and the opportunity to get conspirators off her back.
