A small fraction of these circumstellar discs also contain gas, detected in the form of emission lines from various ionic transitions (most commonly the near-infrared Ca\u2009\n                    <jats:sc>II<\/jats:sc>\n                    triplet). All of the 21 known gas discs exhibit double-peaked line profiles characteristic of a rotating flat disc. The mechanism behind the generation of gas is still debated, but for at least one system it has been linked with the presence of a surviving planetesimal embedded within the dust disc. Here we report the discovery of WD J132800.85\u2013145019.95, a new gas-disc system that exhibits quadruple-peaked instead of double-peaked line profiles. These emission lines originate from two separate gaseous rings extending from 0.14\u2009\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sub>\u2299<\/jats:sub>\n                    to 0.34\u2009\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sub>\u2299<\/jats:sub>\n                    and from 0.54\u2009\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sub>\u2299<\/jats:sub>\n                    to 1.93\u2009\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sub>\u2299<\/jats:sub>\n                    . We propose that this structure results from the presence of two distinct planetary bodies within these discs, ranging in size from a few kilometres to the size of Pluto.
