BERLIN, Sept 30 (Reuters) - German Chancellor Angela Merkel will propose holding exploratory talks about a possible governing coalition with the Greens as well as a meeting already scheduled with the main opposition Social Democrats (SPD), a senior party official said on Monday.
Hermann Groehe, general secretary of Merkel's Christian Democrats (CDU), told reporters the chancellor would contact the environmentalist Greens party - the smallest in the Bundestag since the Sept. 22 election - on Monday or Tuesday.
The talks could take place next week, Groehe added.
Merkel is searching for a new coalition partner, having fallen just short of an absolute majority in the lower house of parliament, but faces difficult and protracted negotiations with a cautious opposition.
First exploratory talks with the centre-left SPD will take place on Friday at 1100 GMT.
