On Monday 18 September, the British government published a new negotiation document on the relationship the UK should have with the EU as regards security, criminal justice and application of the law.
A few days after a new terrorist attack on the London underground, and four days from the speech British Prime Minister Theresa May will deliver in Florence, Italy, London is calling on the EU for a 'treaty' that might enable police, security and criminal cooperation to be continued, and for operational gaps to be avoided after Brexit.
Setting out what already exists in terms of cooperation between the services of the member states and participation in European tools, like the Schengen Information System (SIS), London says that it wants to build on this body of existing arrangements, but in a more developed way than that the EU currently has with third countries. London will therefore seek a more "ambitious" model of cooperation.
Agreements picking up on the models of Schengen-associated country are possible, with London highlighting that these models do not involve the European Court of Justice.
Boris Johnson's article
In an article in the Daily Telegraph on 15 September, the British foreign secretary Boris Johnson called for a clear break with the EU and seems to oppose May on the line to be followed. In particular, Johnson said he would rule out having to pay to have access to the single market. (Original version in French by Solenn Paulic)
