Charities are being invited to make use of a free monitoring service that can alert them when an MP or peer mentions them on Twitter.
PoliMonitor, which has been set up by the lobbying firm Westminster Public Affairs, allows users to create up to five alerts that will generate a daily email each time there are new tweets from parliamentarians matching a particular search.
Searches can be refined to include tweets from MPs, peers, members of the European parliament or members of the Welsh, Northern Irish or London assemblies, or any combination of those categories.
Sam Cunningham, co-founder of PoliMonitor, said: "With MPs tweeting several hundred thousand times a year, we wanted to create an easy-to-use tool that allows charities to stay on top of the debates that matter most to them without having to pay anything for it."
Cunningham said that since the beta launch of the site last week, more than 500 people had signed up for alerts from it and more than 6,000 searches had taken place.
