Prime Minister Theresa May has arrived at her first European Union summit with a "very clear message" for her fellow leaders: Britain is leaving the EU but we'll still help out while we're here.
"The U.K. is leaving the EU, but we will continue to play a full role until we leave and we will be a strong and dependable partner after we have left," May told journalists in Brussels as she arrived for her first European meeting.
"It's in the interests both the U.K. and the EU that we continue to work closely together, including at this summit. We must show a robust and united European stance in the face of Russian aggression," May added.
The 28 leaders are gathering in the Belgian capital for two days. They will mainly discuss how to deal with the Russian involvement in Syria, how to ensure that a trade deal with Canada receives full backing across the union, and will, once again, assess the state of the refugee crisis.
May will brief her EU counterparts Thursday night on her views on Brexit, but there will not be any discussions on the future relationship between the EU and the U.K.
"We expect PM May to intervene shortly during the dinner to present her views on Brexit," an EU official told CNBC in an email.
"No debate expected."
