Mitsotakis heads to US Tuesday for seven days
The leader of the main conservative opposition New Democracy, Kyriakos Mitsotakis, is to begin a seven-day visit to the US on Tuesday.
Mitsotakis, whose party is leading leftist SYRIZA in polls by a wide margin, has been pushing for snap elections.
On Thursday, Mitsotakis is to give a speech at Harvard University, outlining his vision for a return to growth in Greece after seven years of recession.
