Brent council will integrate Twitter with the live streaming of council meetings, as part of Local Democracy Week 2013.
The council will be the first local authority in London to enable people watching the webcasts to tweet messages to the council. Councillors at the meeting will be able to reply to messages live in a Question Time-style evening on 14 October.
James Denselow, Brent's lead member for customers and citizens, said: 'It is crucial for a healthy democracy that residents are aware of what their representatives are discussing at the civic centre.
'I hope that being able to watch council meetings from the comfort of your own home encourages more residents to get involved and use social media to contribute to the debate.'
