Theresa May has received a boost after Austria agreed that Brexit would be among topics for discussion at an informal meeting of EU leaders.
Downing Street said Chancellor Sebastian Kurz agreed that Britain’s departure from the EU would be on the agenda for the European Council being hosted by his country – which currently holds the EU presidency – on September 20.
It means that the Prime Minister has an extra gathering of leaders of the EU 27 in which to convince them to support her Brexit plan after a week in which ministers have been deployed to various capitals to woo senior politicians.
The next meeting is a gathering of EU leaders in Brussels in October by which time it has been hoped a Brexit deal will be hammered out.
Mrs May was dealt a blow by Brussels on Thursday as its chief Brexit negotiator, Michel Barnier, rejected the customs proposals that form a key plank of her White Paper.
A Downing Street spokesman said: “Following their dinner at Downing Street three weeks earlier, the Prime Minister and Austrian Chancellor Sebastian Kurz had a positive conversation ahead of the Salzburg Festival.
“The Prime Minister updated on the White Paper, and Chancellor Kurz confirmed that Brexit would be on the agenda for the informal European Council which Austria would host on 20 September.”
Mrs May also pitched her deal planning to her Czech and Estonian counterparts, Andrej Babis and Juri Ratas, during talks at the Salzburg Festival.
Mrs May attended the music event before heading off to Italy for the start of her summer holidays.
Ahead of their meeting, Mr Kurz said it was important to “avoid a hard Brexit”.
