Germany's opposition conservatives won parliamentary approval on Wednesday for a proposal to drastically restrict migration with the help of votes from the Alternative for Germany (AfD), breaking a taboo on cooperation with the far-right.

Opening the door to leaning on support from the far-right is a gamble for Merz, who believes that his increasingly radical stance on migration will win back right-wingers who are tempted to vote for the AfD. But in so doing, he could risk losing support from the centre.

German election frontrunner Friedrich Merz succeeded on Wednesday in getting a motion passed in parliament that calls for a migration crackdown including the rejection of asylum seekers at the country's land borders.
