PARIS (Reuters) - Far-right leader Marine Le Pen on Thursday said the lone-wolf attack outside parliament in London underscored the need for tighter border controls, as France shuddered at an incident that reopened wounds inflicted by similar assaults at home.

Security is a major campaign issue ahead of next month's close-fought presidential election, in which Le Pen is seen reaching the second round on a nationalist, anti-immigration platform.
