Kiel (dpa / lno) - 46 delegates from Schleswig-Holstein are involved in the decision on the new chairman of the CDU this Saturday.

A total of 1001 Christian Democrats will determine Annegret Kramp-Karrenbauer's successor.

According to party circles in the north, North Rhine-Westphalia's Prime Minister Armin Laschet and ex-Federal Environment Minister Norbert Röttgen could be more likely to be ahead of the former Union parliamentary group leader Friedrich Merz.

But there is no clear picture of the mood.

Prime Minister Daniel Günther had his counterpart Laschet backed in December and confirmed his preference for his team with Federal Health Minister Jens Spahn.

Günther had repeatedly made clear distance to Merz in the past.

Another prominent CDU man from the north supports Röttgen's application with today's Union faction vice-president Johann Wadephul.

Wadephul, once chairman of the North CDU and later of the parliamentary group in Kiel, leads the regional group of Christian Democrats in the Bundestag.

Röttgen's support team also includes the Kiel CDU member of the state parliament, Tobias von der Heide.

"For me, as CDU chairman, Norbert Röttgen is the best choice," he wrote on Facebook.
