ANKARA, Aug 26 (Reuters) - Prime Minister Ahmet Davutoglu invited high profile opposition figures to join an interim cabinet on Wednesday, two months before a snap election at which his ruling AK Party may not recover its parliamentary majority. The main opposition CHP and nationalist MHP had said they would not join the temporary government, but by reaching out to respected figures among their ranks, Davutoglu appeared to be trying to show he was serious about sharing power.
