The Prime Minister has faced a string of Commons defeats in recent months, travelling back and forth to Brussels to negotiate a withdrawal agreement as Britain prepares to leave the EU. Mrs May has faced a strong backlash from her MPs, trying to pass her deal through the Commons on two occasions but so far failing to gain enough votes. On 12 March, Mrs May lost her voice as she struggled to address the Commons, after her deal lost by 149 votes.
Commons officials have prepared an emergency protocol in the event of Mrs May becoming unwell while at the dispatch box.
One insider told The Sun newspaper: “They were so worried about her collapsing that they put a protocol plan in place.
“They had a plan if she fainted to get her out of there.”
The Prime Minister recently returned from Strasbourg with a hoarse voice as she introduced her motion to Parliament.
The next day, Mrs May struggled to get through Prime Minister’s Questions and delegated speeches to her ministers so she could recover from her illness.
The Prime Minister, who is a type 1 diabetic, has previously revealed she takes insulin injections everyday.
Speaking to LBC last November, she said: “Well if you’re stressed if there’s a lot of adrenaline it will tend to go up but you manage that with the amount of insulin you’re putting in.”
There are rising speculations Chancellor Philip Hammond and de facto Deputy Prime minister David Lidington have plans to unseat Mrs May as Prime Minister.
However, David Lidington, has said he has no desire to take over from Theresa May.
He told reporters in his Aylesbury constituency: “I don’t think that I’ve any wish to take over from the PM (who) I think is doing a fantastic job.
“I tell you this: one thing that working closely with the Prime Minister does is cure you completely of any lingering shred of ambition to want to do that task.
“I have absolute admiration for the way she is going about it.”
Meanwhile, Chancellor Philip Hammond told Sky’s Sophy Ridge on Sunday: “This is not about the Prime Minister… changing prime ministers wouldn’t help, changing the party of Government wouldn’t help.”
He added: “To be talking about changing the players on the board, frankly, is self indulgent at this time.”
