Two brilliant Newcastle goals shocked Europe-chasing Leicester City, as the travelling Magpies earned a third straight win to take them ten points clear of the relegation zone.
Jonjo Shelvey showed superb composure on the edge of the box to open the scoring after 18 minutes.
The King Power faithful were outraged as Riyad Mahrez was denied a first-half penalty when Paul Dummett appeared to upend the Algerian.
But the crucial second goal went to Rafa Benitez's side. A mix-up between Wes Morgan, Harry Maguire and Kasper Schmeichel gave Ayoze Perez the opportunity to send a perfectly executed lob over the Foxes keeper with 15 minutes remaining.
