PARIS (AP) — Emmanuel Macron and Marine Le Pen are preparing for their one-on-one televised French presidential election debate, with much at stake for both contenders.

They are expected to square off for more than two hours Wednesday in their final showdown before Sunday’s runoff vote.

The latest opinion polls show the pro-EU Macron holding a strong lead over his far-right rival Le Pen.

Macron, who has been criticized for his early celebrations after he finished nearly three points ahead of Le Pen in the first-round vote April 23, needs to convince leftist voters that his pro-business and liberal stance should not deter them from supporting him. Le Pen is expected to hammer home her favorite themes of security and identity.
