UK 'biggest audience' in Europe for jihadist web content per BBC News

The BBC report http://www.bbc.co.uk/news/uk-41313312 with a straight face that:

'Online jihadist propaganda attracts more clicks in the UK than any other country in Europe, a report has found.

Britain is the fifth-biggest audience in the world for extremist content after Turkey, the US, Saudi Arabia and Iraq, Policy Exchanges study said.

The think tank suggested the UK public would support new laws criminalising reading content that glorifies terror.

The government has told internet companies like Facebook and Google to do more to to remove jihadist material.

Former US military chief General David Petraeus, who wrote a foreword to the report, said efforts to combat online extremism were "inadequate".

He said the bombing of a London Tube train last week "merely underscored once again the ever-present nature of this threat."

"There is no doubting the urgency of this matter," he said."The status quo clearly is unacceptable."'

Why does the UK feature so high in that list? I suppose that the BBC blame a combination of the legacy of empire, Brexit and President Donald Trump, but certainly not Islam.
