    <subfield code="a">&lt;p&gt;Thanks to its long photometric stares, PLATO will likely identify multiple&amp;nbsp;transiting circumbinary planets. However the duration of its long stares are&amp;nbsp;insufficient to measure circumbinary planet masses accurately using eclipse&amp;nbsp;timing variations of the central binary. In this talk I show our efforts&amp;nbsp;on HARPS and SOPHIE to detect circumbinary planets orbiting single-lined&amp;nbsp;eclipse binaries. I will show the first ground-based detections of&amp;nbsp;circumbinary planets made by SOPHIE, HARPS in radial-velocities, and the&lt;br&gt;
first circumbinary planet transit obtained from ground, using ASTEP in&amp;nbsp;Antarctica. The methods we are developing are key to prepare for the&amp;nbsp;confirmation of PLATO&amp;#39;s circumbinary planets.&lt;br&gt;
