Nigel Farage called attacks 'the Merkel legacy', hit out at Brendan Cox and angered the internet

Updated: 

Deadly horrors like the one in Berlin will be Angela Merkel's legacy, according to Nigel Farage.

That was the sentiment the former Ukip leader chose to express this morning as the world came to terms with an apparent terrorist attack that left 12 people dead at a Christmas market.

Farage's tweet appeared to be based on the fact that the driver of the truck is thought to be an asylum seeker.

A "suspicious person", thought to be the driver, was arrested near the scene, authorities said.

Security sources believe he is a 23-year-old Pakistani asylum seeker named Navid B, according to German media, who is reported to have arrived in Germany after crossing the border in Passau, Bavaria, on February 11 this year.

Among the first to react to Farage's tweet was Jo Cox's widower Brendan.

And others agreed that with him that Farage's comments were misjudged or, at best, mistimed.

Some saw it in the context of Farage's desire to be some sort of UK ambassador to America working alongside his friend Donald Trump.

Meanwhile, Farage hit back at Cox.

Asked about it on LBC, Farage said: "Of course he would know more about extremesists than me, Mr Cox - he backs organisations like Hope Not Hate who masqueade as being lovely and peaceful but actually pursue violent and very undemocratic means.

"I'm sorry, Mr Cox, but it is time people started to take responsibility for what happened.

"Ms Merkel has been directly responsible for a whole range of of social and terrorist problems in Germany. It's about time we confronted that truth."

Germany admitted almost 900,000 migrants in 2015 but has tightened up its immigration policy of late.
