BRUSSELS (Reuters) - Britain has failed to win a guarantee of access to EU security databases once it leaves the European Union, according to a draft deal agreed between London and Brussels on future ties, leaving such co-operation open to negotiation.

Britain, along with France, is one of Europe's biggest military powers and hoped that security would be one of its bargaining chips as it seeks a new relationship with the EU, calling for a defence and security treaty in 2019.
