The Prime Minister has been urged to convene urgent political talks in Northern Ireland in the wake of recent street disorder. Labour shadow Northern Ireland secretary Louise Haigh insisted Boris Johnson could not be a “casual observer” to the violence, claiming his Brexit strategy was one of the main factors behind rioting that has predominantly flared in loyalist working class areas. Ms Haigh was responding to a parliamentary statement on the disturbances from Northern Ireland Secretary Brandon Lewis. Mr Lewis said rioting that resulted in almost 90 police officers sustaining injuries was “totally unacceptable” and “utterly reprehensible”. The exchanges at Westminster came as Stormont’s Economy Minister Diane Dodds told the Assembly in Belfast that she did not think the disorder would put off potential investors in the region.
