Understanding the radio emission mechanism from radio quiet quasars is critical for a full understanding of the role of feedback mechanisms during galaxy evolution. In order to directly image the radio emission of these sources, we are using strong gravitational lenses as cosmic telescopes that magnify background source emission. Our programme so far has revealed a mixed picture, with radio emission appearing to originate variously from star formation in quasar hosts and from activity associated with the AGN engine. One source from our sample has previously been observed using the EVN and eMERLIN, revealing twin mini jets either side of the AGN core. This source has also been found to feature a low gas fraction, indicative of star-formation quenching, in addition to relativistic large-scale winds. In order to build a picture of how these phenomena may be linked, we propose a second EVN+eMERLIN observation of the system, which will allow us to determine the existence or otherwise of relativistic motion of the jets and further develop the model of AGN feedback in radio quiet host galaxies.
