Theresa May's horror day ahead

Theresa May is gearing up for one of the most difficult days of her tenure.

She faces grillings from the Opposition, her own MPs, a possible "Geoffrey Howe" moment from Boris Johnson - and, to cap it all, drinks this evening with Britain's political news reporters.

Here's how her Wednesday diary looks:

12 noon Prime Minister's Questions - These sessions are getting longer and longer. Brexit will be the focus of intense scrutiny from the other political parties.

2pm Debate - This is on the future relationship between the UK and EU. The big question is will Boris Johnson take the opportunity to make a statement about his resignation as foreign secretary? This could pile even more pressure on Mrs May.

3pm Liaison Committee - Mrs May faces a grilling from the senior MPs who chair Commons select committees across all different subjects.

6pm 1922 Committee - This influential group of Tory backbench MPs can be vocal and difficult for their leaders. Any letters calling for a no confidence vote in the leader are lodged with chairman Graham Brady.

7pm Drinks - Awkward timing for this social event with leading political journalists.
