from Truss will insist on unity of European leaders to “tackle the root causes” of energy and migration challenges after days of tackling splits within her government.
Prime Minister will attend a summit of European leaders in Prague on Thursday, with the French president Emmanuel Macron among those she expects to meet.
Mrs. Truss travels to the Czech Republic for the European Political Community meeting following a difficult Conservative Party conference dominated by internal divisions and backstabbing opposition to some of its major policies.
She is expected to meet with the French prime minister for a bilateral meeting after holding talks with him at a UN summit in New York last month.
Downing Street says Ms Truss’ talks with Mr Macron and Dutch Prime Minister Mark Rutte will focus on migration and aim to secure progress in joint operations to disrupt human trafficking gangs.
10 adds that the prime minister will also encourage countries to act more quickly to end Europe’s reliance on Russian energy supplies in the face of Ukraine’s renewed invasion.
Ms Truss is expected to say at the opening plenary session in Prague: “Europe is facing its worst crisis since the Second World War. And we faced it together with unity and determination.
“We must remain steadfast – to ensure Ukraine wins this war, but also to face the strategic challenges it has exposed.”
Ms Truss will try to highlight the UK’s role in European affairs – including Ukraine – despite leaving the EU, Downing Street said.
The Prime Minister will say: “The threat has lasted far too long. Now we are finally tackling Putin’s aggression.
“And we should take the same approach with other challenges ahead – including long-standing regional issues such as energy and migration.
“Instead of the old approach that only tackled the symptoms, it’s time to tackle the root causes.”
Ms Truss is expected to attend a working lunch with Czech Prime Minister Petr Fiala.
As Secretary of State, she was skeptical of the planned summit, so her decision to attend came as some surprise.
