This warm March is in huge contrast to March last year - the second coldest on record.
Nick Clegg is hoping that there are votes to pick up in being the clearest voice on the pro-Europe side of the debate.
Liberal Democrat leader Nick Clegg has jumped on the selfie bandwagon with one of his own at his party's spring conference.
Around 1,000 anti-fracking demonstrators have marched through Manchester in what organisers described as a "party atmosphere".
The protesters gathered in Piccadilly Gardens, in the city centre, before moving to Cathedral Gardens for speeches.
The event is thought to have been one of the biggest protests yet in the UK against the controversial shale gas extraction process.
Those taking part included members of the protest camp at Barton Moss, in Eccles, Salford, where test drilling is being carried out.
Greater Manchester Police tweeted:
Thanks to those who organised or took part in today's protest - around 1,000 people took part and we didn't have to make any arrests
Gravesend in Kent had the highest temperature in the country today, recording 20.5C (68.9F) at 2.30pm, according to the Met Office.
The last time the 20C mark was breached in Britain was on October 8 last year.
Nick Clegg intends to remain as Liberal Democrat leader until at least 2020 - whether or not the party is in power - his office said today as speculation about the Deputy Prime Minister's future overshadowed his spring conference speech.
The Deputy Prime Minister was forced to respond to speculation about his future following reports that senior MPs were positioning themselves as possible successors.
"Nick Clegg intends to be the leader of the Liberal Democrats today, tomorrow, into the 2015 election and through the whole of the next parliament," a spokesman said.
"He intends to be leader of the Liberal Democrats whether or not we are in government."
A Ministry of Justice spokeswoman said: "The Government believes that any change to the law in this emotive and contentious area is an issue of individual conscience and a matter for Parliament to decide rather than Government policy."
A Liberal Democrat MP wore a Nigel Farage mask at the party's conference as she mocked the Ukip leader's penchant for beer.
Just before Nick Clegg's appearance, Lorely Burt also mocked a former-Ukip councillor's claim that this winter's floods had been brought on by the introduction of gay marriage.
The Liberal Democrats are the only guardians of a "modern, open and tolerant Britain", leader Nick Clegg has said to the party's spring conference.
Mr Clegg defended his party's role in the coalition government, and said the party must remain in power after next year's general election to ensure the "reconstruction and renewal" of the country.
The deputy prime minister added that, though many "still feel the squeeze" of the recent economic downturn, British people can "finally see the light at the end of the tunnel".
Nick Clegg has aimed fire at Nigel Farage and Ukip for their "politics of blame" in his closing speech at the Liberal Democrats' spring conference in York.
As some polls indicate eurosceptic Ukip may overtake the Lib Dems in May's European elections, Clegg said: "Do you want Britain in or out [of the EU]? That's the real question in May."
Many of us will have a perfect spring day with unbroken, clear blue skies and sunshine.
More cloud will remain across the north-west with dull, damp conditions for Scotland and Northern Ireland - the rain pepping up later.
Away from the cloud in the north-west, a remarkably mild climate for the time of year and people will be feeling warm in the south, with temperatures peaking at 17-18C inland - and possibly 19C. Coasts will be prone to a cool sea breeze.
The former leader of the House of Lords this week called for a change in the law to allow terminally ill patients to die with the assistance of medical professionals.
While guidance from the director of public prosecutions suggests that loved ones who end the lives of terminally ill adults should not be prosecuted. However, assistance from professionals remains prohibited.
Speaking on Friday, Baroness Jay of Paddington questioned whether it was sensible for parliament "to condone compassionate amateur assistance to die while prohibiting professional medical assistance which might be equally compassionate and more skilfully gentle".
A bill on assisted dying put forward by Labour's Lord Falconer proposes reforms to allow "safeguarded choice" for "mentally competent" terminally ill patients with six months to live. A Lords vote is expected on the bill in the next four months.
