Allies of Jeremy Corbyn are plotting to oust up to 50 moderate Labour MPs, according to the lead story in the Sunday Times.
It says they want to see more left leaning MPs take their place. The left-wing grass roots movement Momentum tells the paper it is not campaigning for the deselection of any sitting members of parliament.

Finally, the Sunday Telegraph finds that Kazakhstan’s attempts to assert their autonomy from Russia by replacing their old Cyrillic alphabet with Latin characters has “hit an unlikely snag”; the apostrophe.
The difficulties of rendering Kazakh words in their new form mean that, of the 32 letters in the new alphabet, nine have an apostrophe. It has sparked rare dissent in the authoritarian country.
