There’s certainly no shortage of discussion material for Theresa May's Brexit cabinet as it meets in Downing Street.

Speculation about the (renewed) peril in which Mrs May finds her leadership, continued Conservative Party in-fighting over Brexit, simmering scandal around another member of Mrs Mays cabinet - and that’s just for starters.

Mrs May's hold on the Tory leadership has been precarious since the disastrous result for her party in last year’s general election. 

Her government has limped forward carrying the weight of Brexit, but not much else. It has proven impossible to drive through any other agenda which the Prime Minister might want.

Some of the crises have been of Mrs May's own making - the gamble of calling a general election when she didn't really need to, a disastrous reshuffle in recent weeks in which some ministers managed to argue their way back into roles from which she wanted to move them.

By the same token, some of the crises have been outside of her control - a coughing fit at the Conservative Party conference, the election of a US President upon whose goodwill many in government feel unable to depend.

In the middle of all this Mrs May has kept the Conservative Party show on the road as she desperately tries to balance a cabinet, a party and a country which is utterly divided on the biggest political issue of the day - Brexit.

The Prime Ministers mantra during the election campaign was "strong and stable". But that is now seen as weak and dull. It was that description of her leadership as dull last week by a number of her own MPs which has added to whispers her leadership is faltering.

Combine that with reports that the chairman of the Conservative Party has received approximately 40 letters from MPs asking for a leadership contest and the whisper becomes a loud voice. 

The key number in that issue is 48 - once 48 Conservative MPs have written such a letter then a leadership contest must be automatically triggered. It moves ever closer.

But remember the fundamentals remain the same - Mrs May has lasted this long because many MPs see no viable alternative as a leadership candidate. That has not changed.

The "big beasts" of Mrs May's cabinet are unable to agree. A comment from Chancellor Philip Hammond last week in Davos that Britain would only be "very modestly" moving away from the EU post-Brexit caused consternation among Brexiteers.

There are also concerns about the transition or implementation deal which is currently under discussion.

Fears among Brexiteers that it may last longer than two years continue.

Every day brings another report of some wing of the Conservative Party unhappy with the direction in which Brexit is going.  

This tug of war between pro and anti-Brexiteers makes clashes constant and unity unfeasible. 

Their disagreements may make Mrs May's leadership last longer - although how much longer would be anyone’s guess.
