The Tory leader will also meet EU chief Jean-Claude Juncker where she will seek changes to the Irish backstop, one of the most contentious parts of the withdrawal agreement she agreed in November. Theresa May has told EU leaders she could pass her deal with concessions primarily around the backstop - a guarantee that there can be no return to border controls between the British province of Northern Ireland and EU-member Ireland.
But a defeat in a symbolic vote in parliament on Thursday has weakened her pledge and increase the risk of a "no-deal" Brexit in 40 days.
The backstop has become one of the main points of contention ahead of Britain's planned departure from the EU next month after 45 years.
In a letter to her divided Conservative MPs, Mrs May asked them to put aside "personal preferences" and unite in the interests of the country by backing a deal.
She wrote: ”Our party can do what it has done so often in the past: move beyond what divides us and come together behind what unites us; sacrifice if necessary our own personal preferences in the higher service of the national interest.”
