Home Secretary Suella Braverman is to quiz Met chief Sir Mark Rowley chief about the force's response to incidents during a pro-Palestinian protest.
A video posted online appeared to show a man chanting "jihad" during a rally by an Islamist group in London.
The Met said no offences were identified in the clip, which occurred at a separate event from the main march and was staged by Hizb ut-Tahrir.
Sir Mark is expected to say current laws make prosecutions difficult.
The meeting between Mrs Braverman and the Met Police chief was already in the diary to discuss the ongoing protests and combating anti-Semitism.
But a source close to the home secretary said she would use it to question Sir Mark for his views on his force's response to Saturday's incident.
The source said there could be "no place for incitement to hatred or violence on Britain's streets".
