The report says that a top Conservative lawmaker will tell Theresa May in the coming week that she has to quit by the end of June or else the party's members will try again to oust her in the coming months.
Just be reminded that May did survive the last leadership challenge back in December, which means that her position as party leader cannot be challenged until a year has passed. However, the report here notes that 1922 Committee chair, Graham Brady, is also on board with trying to depose May - as he reportedly will tell her that the rules to that will change unless she decides to resign.
This is the latest development in the Brexit saga but for now, it's mostly a bunch of rumours. Let's see if other sources will pick up on this later in the week. Other than that, we're still faced with the earlier impasse as the government continues to hold talks with the Labour party to try and find a breakthrough.
