LONDON (Reuters) - After a militant attack on a nightlife district of London this weekend, British Prime Minister Theresa May will resume campaigning on Monday just three days before a national election which polls show is much tighter than previously predicted.

May said Britain must be tougher in stamping out Islamist extremism after three knife-wielding assailants rammed a hired van into pedestrians on London Bridge and stabbed others nearby, killing seven people and injuring 48.
