Largest democratic exercise

Mrs May's speech to the National Conservative Convention in Oxford on Saturday evening came as MPs prepare for a series of votes on Wednesday which could see Parliament take control of the Brexit process.

Delegates at the convention overwhelmingly backed a symbolic motion saying Brexit should not be delayed, and leaving without an agreement should remain an option.

Mr Clark, the business secretary, along with Ms Rudd, the work and pensions secretary, and the justice secretary, Mr Gauke, had earlier said they would be prepared to defy Mrs May and vote for a delay to Brexit.

They argued there "simply will not be time to agree a deal and complete all the necessary legislation" unless a deal is approved in the coming days.

An amendment tabled by former Tory minister Sir Oliver Letwin and Labour's Yvette Cooper would give Parliament the opportunity to delay Brexit and prevent a no-deal situation if there is no agreement with the EU by the middle of March.

But Mrs May told activists: "Our focus to deliver Brexit must be absolute.

"We must not, and I will not, frustrate what was the largest democratic exercise in this country's history. In the very final stages of this process, the worst thing we could do is lose our focus."

Mrs May also said there should be no moves to deselect MPs because of their views on Brexit.

Brexit must not be frustrated, Theresa May vows

The Brexit vote must not be frustrated and the government needs to maintain an "absolute" focus on delivering it, Theresa May has said.

In a speech to Tory activists the PM said, as her negotiations with the EU reach their final stages, the "worst thing we could do is lose our focus".

It came as three pro-EU cabinet members warned they could vote to delay Brexit to prevent a "disastrous" no-deal.

But Mrs May said there must be no party "purges" over MPs with differing views.

Ahead of crucial votes in the Commons next week, Greg Clark, Amber Rudd and David Gauke told the Daily Mail they would be prepared to defy the prime minister and vote for a delay.

The intervention led to calls for their resignations by Tory Brexiteers.

The sorry fate of North Korea's diplomat defectors

But just a few days ago, President Trump said he was "in no rush" to press denuclearisation.

One possibility mooted is a declaration to officially end the Korean War. Some suggest the US will ask North Korea to put forward concrete steps, such as dismantling the Yongbyon nuclear site and missile bases, in exchange for some US sanctions relief.

So what can we expect this time round

This time round both leaders will be very conscious that expectations will be high for an outcome that demonstrates tangible signs of progress - or at least a measurable roadmap for progress.

Analysts will watch closely what concessions both sides are prepared to make for this.

Washington's original stance was that North Korea had to unilaterally give up its nuclear weapons before there could be any sanctions relief.

Why Kim will be looking closely at Vietnam

• Why Kim will be looking closely at Vietnam

Moves like the dismantling of a key rocket site in the North last summer are little more more than a gesture, experts say, given the North made no commitment to halt weapons development or shut down missile bases.

However, lower-level negotiation channels have recently seen activity, which could mean more goes into a Hanoi declaration.

North Korean leader Kim Jong-un

North Korean leader Kim Jong-un has departed for Hanoi by train for talks with US President Donald Trump.

He arrived at the Chinese border city of Dandong after 21:00 local time (13:00 GMT) on Saturday.

The much anticipated second US-North Korea summit is scheduled for Wednesday and Thursday in the Vietnamese capital.

It follows a historic first round of talks last year in Singapore. All eyes will be on what if any progress is made towards "denuclearisation".

The departure, confirmed by North Korean state media, is the first official acknowledgement that the talks are taking place.

The state media report said Mr Kim would pay a "goodwill" visit to Vietnam as part of the trip.

He is thought to be travelling with his sister Kim Yo Jong and one of his key negotiators, former General Kim Yong Chol

another kind is actual video spam

Yet another kind is actual video spam, giving the uploaded movie a name and description with a popular figure or event that is likely to draw attention, or within the video has a certain image timed to come up as the video's thumbnail image to mislead the viewer, such as a still image from a feature film

Video sharing sites

Video sharing sites, such as YouTube, are now frequently targeted by spammers. The most common technique involves spammers (or spambots) posting links to sites, on the comments section of random videos or user profiles. With the addition of a "thumbs up/thumbs down" feature, groups of spambots may constantly "thumbs up" a comment, getting it into the top comments section and making the message more visible.

Blog spam is spamming on weblogs

Blog spam is spamming on weblogs. In 2003, this type of spam took advantage of the open nature of comments in the blogging software Movable Type by repeatedly placing comments to various blog posts that provided nothing more than a link to the spammer's commercial web site.^[ Similar attacks are often performed against wikis and guestbooks, both of which accept user contributions. Another possible form of spam in blogs is the spamming of a certain tag on websites such as Tumblr.
