Threat of terrorism split in Brexit debate

Conflicting arguments have emerged over the whether Brexit will impact the UK's exposure to terrorism. Work and Pensions Secretary Iain Duncan Smith, a Brexit supporter, argued that staying in the Union exposes the country to a higher risk from terrorism, stating that “the lack of any control on our borders is a critical issue”. Prime Minister David Cameron subsequently rejected this, arguing that the UK is “safer and stronger” in the EU. Supporting his position, Foreign Secretary Phillip Hammond was quoted in a newspaper article saying “leaving the EU would be a threat to our [the UK’s] economic security and our national security”. Meanwhile, Europol’s director, Rob Wainwright, argued the British police would find it harder to prevent militant attacks if the country left the EU.

EU row: Cameron has 'low opinion of British people'

Work and Pensions Secretary Iain Duncan Smith has accused the Prime Minister of having "a low opinion of the British people" by downplaying the UK's prospects if it left the EU.

It comes after a Sunday newspaper column in which David Cameron accused MPs backing an EU exit of wanting to take "the gamble of the century" with the country's future.

Amid rising tensions between the pro- and anti-Brexit camps, Mr Cameron has reportedly been threatened with a challenge to his leadership unless he tones down attacks on MPs backing the "leave" campaign.
