As Germany heads to parliamentary polls on Sunday (February 23), the spotlight will be firmly placed on the divisive far-right party, the Alternative for Germany (AfD) and its leader, Alice Weidel.

The leader of the Alternative for Germany (AfD) party has been endorsed by Donald Trump - and looks set to make huge gains in this weekend's snap election.

Germans will head to the polls Sunday looking for leadership at a deeply uncertain time, but all eyes will be trained on a party likely to finish a distant second.

A snap election was called at the end of last year by current Chancellor Olaf Scholz, of the Social Democratic Party (SPD), when his coalition Government fell apart.
