May not expecting a 'breakthrough' on Brexit at EU summit

May has arrived at the EU summit after surviving a vote of confidence organized by the lawmakers from her Conservative Party.

"What I will be talking to European leaders about here today is about what I think we need to get this deal over the line ... I will be showing the legal and political assurances that I believe we need to assuage the concerns that members of parliament have on this issue ... I don't expect an immediate breakthrough but what I do hope is that we can start the work as quickly as possible on the assurances that are necessary," May told reporters.

The UK prime minister also said she would not lead the Conservative Party into the next general election scheduled for May 2022.

On Monday, May said she was postponing a parliamentary vote on her Brexit deal with the European Union, which was originally scheduled for Tuesday, amid lawmakers' concerns over the Irish border backstop.
