LONDON (AP) — The Latest on Britain's departure from the European Union (all times local):

3:15 p.m.

The top civil servant on Britain's Brexit negotiating team has left the Department for Exiting the European Union in what opponents said was a sign of chaos in Britain's Conservative government.

The department says Oliver Robbins is moving to become British Prime Minister Theresa May's EU adviser. It says he will continue to lead the team of British officials at negotiations with the bloc.

The shift follows reports of friction between Robbins and Brexit Secretary David Davis and comes a week before negotiations on Britain's divorce from the bloc are due to resume in Brussels.

Opposition Labour Party Brexit spokesman Keir Starmer said the shuffle "adds a whole new dimension to government's chaotic approach to Brexit."

Philip Rycroft is replacing Robbins as the top civil servant in the Brexit department.

The British government says it wants a wide-ranging security treaty with the European Union that would give it continued access to intelligence-sharing and law-enforcement cooperation after Brexit.

In a paper released Monday, the government called for "a comprehensive new security, law enforcement and criminal justice partnership" with the EU.

Such a deal would allow Britain to remain a member of the EU police body Europol and maintain use of the European Arrest Warrant, which allows for the quick extradition of criminal suspects.

Brexit Secretary David Davis says of the proposal: "Cross-border cooperation is absolutely crucial, if we're to keep our citizens safe and bring criminals to justice."

Britain is publishing papers on various aspects of Brexit in hopes of unblocking its divorce talks with the EU.

Britain's statistics regulator has accused Foreign Secretary Boris Johnson of misleadingly claiming that leaving the European Union will give Britain an extra 350 million pounds ($475 million) a week to spend on health care.

In an article laying out his vision for Britain's post-Brexit future, Johnson said the U.K. will "take back control of roughly 350 million a week" and much of it could go to the health service.

U.K. Statistics Authority chief David Norgrove chided Johnson, saying it was a gross rather than net figure. It doesn't take into account a substantial rebate Britain receives before the money is sent.

Norgrove called the figure "a gross misuse of official statistics."

Johnson accused Norgrove of distorting his article, but the statistics authority said Monday that Norgrove stood by his opinion.
