Brexit - as it happened: David Davis hails 'significant step' as UK and EU strike draft transition deal

Elections expert Lord Hayward has said the Conservatives could be on course for their worst ever local election results in London, just weeks ahead of the 3 May poll. 

MPs are now listening to today's second Urgent Question, this one asked by Brexit Committee chair Hillary Benn, on the issue of customs arrangements at UK ports after Brexit.

He asks about remarks made by Chris Grayling, the Transport Secretary, to the BBC last week. 

Grayling said: "We don't check lorries now - we're not going to be checking lorries at Dover in the future."

Benn asks how this statement is consistent with the Government insisting it will leave the EU customs union.

Mel Stride, Financial Secretary to the Treasury, says there will not "in any circumstances" be a hard border in Dover that requires every lorry to be stopped. 

Tory MP Douglas Ross isn't happy with today's Brexit deal, saying it would be "easier to get someone to drink a pint of cold sick than try to sell this as a success"...

Make no mistake – Brexit will make it harder for us to combat Russian aggression in the future, writes Labour MP Chuka Umunna.

Both Trump and Putin are threatening the liberal world order, and they need to be robustly challenged. The Prime Minister was right to respond so strongly. But our best weapon against future international aggression is staying in the EU.

MPs have moved onto the final urgent question of the day, which focuses on the alleged breach of Facebook user data by Cambridge Analytica. The firm allegedly mined the profiles of 50m people to create targeted adverts without their knowledge.

Culture Secretary Matt Hancock said the revelations were "clearly very worrying" and said the Information Commissioner was looking into the alleged breaches.

Canvassing voting intention is something that political parties do all the time, he said, but the public must be comfortable in how their information is being used.

Damian Collins, chair of the Culture, Media and Sport Committee, said many people would be "shocked that their data can be harvested in this way", as ticking a box "does not sign away your rights".

He calls for a "broader investigation into Cambridge Analytica as a company" and says someone must have the authority to go behind the curtain to make sure powerful tech firms are complying with data protection laws.

Labour's Liam Byrne says the allegations are "an utter indictment" of the way the Government has allowed tech giants to be "careless and carefree".

He asks if Cambridge Analytica's directors are "fit and proper people" to hold these positions and demands powers for them to be struck off "forthwith".

Former attorney general Dominic Grieve said data was a "goldmine for those who wish to break the law" and insisted the sanctions were "entirely inadequate".

Culture Secretary Matt Hancock said the existing fines were not insignificant and the information commissioners office had strong sanctions for specific actions. He said the point was worth listening to nonetheless. 

Lib Dem former Cabinet minister Ed Davey asks whether there will be a full public inquiry if any evidence emerges that there was interference in a UK election or referendum.

Matt Hancock says there is no evidence there has been successful interference in any elections but "we remain vigilant".
