Brexit news - live: Theresa May heads to France amid howls of outrage from Tory Brexiteers at 'surrender' over customs union

The Home Office has apologised after mistakenly sharing email addresses with a mailing list for the Windrush compensation scheme.

An "administrative error" meant that emails sent to some individuals and organisations who had registered an interest in being kept informed about the launch of the scheme included email addresses of other recipients.

Five batches of emails, each with 100 recipients, were affected. No other personal data was included.

In a written statement, immigration minister Caroline Nokes said: "Regrettably, in promoting the scheme via email to interested parties, an administrative error was made which has meant data protection requirements have not been met, for which the Home Office apologises unreservedly."

Ms Nokes added that a recall was commenced as soon as the problem had been identified. An internal review will be conducted and the department has voluntarily notified the Information Commissioner's Office.

Nearly 40,000 people in the UK are still living in tower blocks wrapped in the same type of flammable cladding which covered Grenfell Tower, new government figures suggest.

Some 16,600 homes across 163 private residential buildings are covered in Aluminium Composite Material (ACM), which was banned in the aftermath of the Grenfell Tower fire, according to the Department of Housing, Communities and Local Government.

The Labour Party, which obtained the figures, estimated 39,840 people were living in the affected buildings nearly two years after 72 people were killed in a blaze at the west London tower block.

Radioactive waste will be piled up above normal safety limits at hospitals, universities and factories because of fears that Brexit will disrupt supply chains.

Ministers are under pressure to own up to any potential risks to health and security, after emergency advice was quietly issued to organisations and businesses.

Under the measure, they are being allowed to bust limits if they are unable to export waste because of Brexit – or if they fear they will be unable to obtain the radioactive material they need.

Taisoeach Leo Varadkar is giving a press conference with Michel Barnier in Dublin.

He says Ireland is open to a delay to Brexit as it wants to ensure a smooth departure. A no-deal scenario would be bad for all involved. Ireland continues to prepare for such an outcome in the face of uncertainty.

Michel Barnier, the EU's chief Brexit negotiator, is up next.

He says the EU wants to respect the parliamentary debate in the UK, and the cross-party talks with Labour.

'We all hope these talks will produce a positive outcome', he says.

He says the political declaration could contain a customs union if the UK wants - and the EU is ready to clarify the document to reflect that. It could happen quickly, he says.

Whatever happens, the EU will stand fully behind Ireland, he says. He also reaffirms his stance that the backstop is the 'only solution' to the Irish border issue.

He also repeats his position that the EU will not negotiate with the UK until the issues of the border, citizens rights and the divorce bill have been sorted - even if there is a no-deal Brexit.

And that's it for the press conference.

Theresa May is due to meet senior members of the Conservative backbench 1922 Committee in Downing Street.

It is understood that it is a regular meeting between the PM and the 1922 executive in No 10.

It's a big week - another one - for Theresa May. What's in store?

Talks are taking place tonight between Labour and government teams, as they seek to break the Brexit deadlock. No white smoke as of yet.

A Labour spokesperson said: “Following further communication between the Brexit negotiating teams over the last 48 hours, Labour Party and government officials are meeting this evening.”

A Downing Street spokesman said: “We have been in touch with the Opposition today and technical talks between officials will take place this evening.”
