The UK and EU begin a new relationship on 1 January 2021.

Did you know she's won a Grammy? Neither did we, so we went on the hunt for some of the potential first female US President's more obscure achievements.

A summary of which MPs have publicly said they will support either the Remain or Leave campaigns in the forthcoming EU referendum.

For the second day running the political news has been dominated by tributes and further reaction to the death of Labour MP Jo Cox, 41, who died after being shot and stabbed outside her constituency surgery in West Yorkshire on Thursday.

Here is a round-up of today's events:

• Prime Minister David Cameron, Labour leader Jeremy Corbyn and other politicians laid wreaths in memory of Mrs Cox at her Batley and Spen constituency 
• West Yorkshire Police said links to right-wing extremism and the mental health of suspect Tommy Mair were lines of inquiry in their investigation into Mrs Cox’s death
• West Yorkshire Police also confirmed it is working with the North East Counter Terrorism Unit on the investigation
• In response to the tragedy, the Remain and Leave groups cancelled campaigning until Sunday 
• Mr Cameron also confirmed Parliament would be recalled on Monday. The House of Lords has also been recalled to pay tribute to Mrs Cox
• The Conservatives, the Lib Dems, UKIP and the Green party said they would not contest the by-election in Batley and Spen
• In separate news, Labour's Rosena Allin-Khan won the Tooting by-election

More than £150,000 has been raised for charities supported by murdered MP Jo Cox. Friends of the late Labour politician are raising money to support the three charities "closest to her heart" and chosen by her family following her death. They represent her campaigns as an MP to help civilians caught up in the Syrian war, to fight racism and extremism in Britain, and to help residents in her Batley and Spen constituency in West Yorkshire.

Politicians have been "inspired to rededicate" themselves to public service following the death of MP Jo Cox, Nicola Sturgeon has said.

Politicians across Scotland held their Friday surgeries as normal despite the death of the Labour MP, who was shot and stabbed after holding a constituency surgery in Birstall.

Ms Sturgeon paid tribute to Ms Cox at a meeting of the British-Irish Council.

Vigil events have been held in Edinburgh and Glasgow.

Conservative MEP Saj Karim has said he has had "very direct threats" made against him, as an MEP, which are currently being investigated by the police.

Speaking to the BBC's North West Tonight, he said:  "There have been very direct threats which are now currently with the police, are being investigated and I anticipate that there are individuals who will be spoken to as a result of those threats."

He said there had been a building up of tensions as the political messaging in the EU referendum campaign had ratcheted up over the course of the last 10 days.

Mr Karim decided to step up security at his home in November 2010 but in the wake of the attack on Jo Cox MP, speaking about the level of security required for politicians, he said:

Vigils have also been held in Glasgow and Edinburgh in memory of Jo Cox.

Addressing the crowd in George Square, Glasgow, Scottish Labour leader Kezia Dugdale paid tribute to someone she said was "the very definition of a moral crusade, wrapped up in humour and love".

A vigil is due to be held in Belfast at midday on Sunday outside the City Hall, the Labour Party in Northern Ireland said.

Former Labour leader Ed Miliband describes Jo Cox as "a fighter for justice" in all that she did, and someone who "showed no fear in the face of danger".

"We remember her too as somebody of the greatest warmth, generosity and compassion," he adds.

He says people should "honour her legacy" of giving "a voice to the voiceless" and "standing up against oppression where she found it".

Former acting Labour leader Harriet Harman follows, and says that although Jo Cox was "a passionately committed campaigner" for the causes of social justice, "she was never divisive".

Everyone must heed the words of her husband, who has said to "unite against the hate that killed her", Ms Harman adds.

She says that when political campaigning resumes, "we will still have our political arguments... but let's think about how Jo did her politics, let's aspire to leave behind the venom and the toxicity and the division".

Beginning the speeches, Labour MP Wes Streeting says friendship and politics are two words "you don't often hear together" but he says they go "hand in hand" and are "more common" than people realise.

He says the solidarity show in the wake of her death has been "overwhelming".
