The Prime Minister has invited the First Minister to a one-to-one summit on Brexit.

Theresa May said last week she wanted both sides to begin discussions following months of no progress and a cooling of relations between the pair.

According to one media report, a letter was sent by the Prime Minister on Sunday but a spokesman for the First Minister said she had not received any written confirmation.

He said an "informal approach" from Downing Street had already been made.

The spokesman added: "The First Minister would be more than happy to meet [the Prime Minister]."

The Scottish Government wants Scotland to remain formally inside the European single market even if the rest of UK leaves but this has been rejected by the UK Government.

When asked about the approach, a spokesman for the Prime Minister said "no further details" are available.

Complaints have also been made about the lack of communication between both governments over a range of issues.

The pair last had a bilateral meeting in March.
