No members of British Prime Minister Theresa May's cabinet challenged her over her so-called Chequers plan for Brexit at a meeting earlier on Monday, a journalist from the Sun reported.

"I am told not a single minister challenged the PM over Chequers during Cabinet today," the Sun's political editor, Tom Newton Dunn, said on Twitter.

The BBC also reported that the cabinet remained fully behind May's Brexit policy in the face of growing calls within her party to change direction.

The prime minister is sticking by her Chequers plan for future cooperation despite European leaders attacking it. She met senior ministers as pressure grows on her to ditch it in favour of a Canada-style trade accord.

Meanwhile, the government said in technical papers published on Monday Britain will allow EU airlines to continue to fly into the country if it leaves the bloc without a divorce deal. Britain has said it wants to continue to participate in the European Aviation Safety Agency, but without a Brexit deal this might not be possible.

The UK government said it was aiming to avoid such a worst-case scenario, and would look for an agreement on flying rights if there was a disorderly Brexit.

"In this scenario the UK would envisage granting permission to EU airlines to continue to operate. We would expect EU countries to reciprocate in turn," it said in the paper.
