Baroness Eliza Manningham-Buller, a former head of security service MI5, told news agency Xinhua that Britain works extraordinarily closely on security in Europe and the UK does not want that to be damaged.&nbsp;</div>''<div><br />''</div>''<div>British Prime Minister Theresa May on Saturday called for talks with the EU about a new security treaty after London left the bloc as she addressed the Munich Security Conference. May told world leaders that Britain and EU must do whatever is most practical and pragmatic in ensuring their collective security.&nbsp;</div>''<div><br />''</div>''<div>Manningham-Buller took the opportunity on the sidelines of a press briefing at the Wellcome Trust, where she is the chair, to underline her support for May's initiative. May hopes Britain can stay closely aligned with EU on security policy.
