The Queen has voiced her frustration with today's politicians and their 'inability to govern correctly', it has been claimed.

The 93-year-old monarch remains scrupulously neutral in public but is said to have told aides of her 'disappointment in the current political class'.

She made the comments in 2016 but her feelings have only intensified since then amid endless political turmoil over Brexit, sources told The Sunday Times.

'[Her Majesty] expressed her exasperation and frustration about the quality of our political leadership, and that frustration will only have grown,' one said.

Royal aides were said to be surprised by her tone, describing the Queen as 'really dismayed' by the state of UK politics.

It comes amid fears that the Queen will be dragged into the political arena in the lead-up to Britain's October 31 Brexit deadline.

Both Brexiteers and opponents of No Deal have threatened to use unprecedented constitutional manoeuvres to get their way.

While the monarch is sovereign, the UK political system relies on her being kept out of politics as much as possible. In normal times her role is a courtesy one, rubber-stamping Government decisions.

However, political conventions have proven flexible in recent months and pro-EU MPs insist the Queen will have no choice but to sack Mr Johnson if a no-confidence motion is passed in the Commons and he refuses to go voluntarily.

'The Queen would write him a letter saying he is dismissed,' one Remainer source insisted. 'She would have to sack him. Of course she would.'

On Wednesday, shadow chancellor John McDonnell warned that if Mr Johnson was defeated in a vote of confidence, Labour would insist on Jeremy Corbyn becoming prime minister.

'I don't want to drag the Queen into this but I would be sending Jeremy Corbyn in a cab to Buckingham Palace to say we're taking over,' he told an event at the Edinburgh Festival Fringe.

Mr Johnson could also use a loophole in the Fixed-Term Parliaments Act to schedule an election for after October 31 if he loses a confidence vote.

The Queen names the date based on recommendation from the PM, but the act does not give any time frame he must work inside.

Pro-EU MPs admit Mr Johnson could legally extend the schedule by at least a month - taking it well beyond the Halloween deadline.

The Queen reportedly made her comments shortly after David Cameron resigned in the wake of the Brexit referendum.

The three years since then have been marked by even greater political upheaval, with both parties major parties divided.

No party has had a majority in the Commons since 2017 and chaos has reigned in Parliament in recent months.

Most significantly, Westminster has been unable to agree on any workable Brexit proposal to implement the result of the 2016 referendum.

MPs voted three times to reject Theresa May's withdrawal agreement with Brussels and she was hounded out of office shortly afterwards.

However, alternative such as No Deal or a second referendum have also failed to win majority support among MPs.

Both major parties were severely punished by voters at the European elections in May with Labour coming third and the Tories a humiliating fifth.
