What security measures are in place for MPs in their constituencies?
MPs' security was a big political issue even before the killing of Labour's Jo Cox in 2016. Following that attack, all MPs were offered panic buttons, extra lighting, additional locks and emergency fobs at their homes and constituency offices.
Prior to that, those wanting enhanced security arrangements had to ask police to carry out a risk assessment and produce written estimates before any work could be carried out.
Official data shows the amount spent on such measures rose from £171,000 in 2015/16 to £4.2m in 2017/18.
Parliament also offers MPs and their staff guidance on security, including tips on how to run a safe constituency surgery, suspicious post and risks at home.
A Parliamentary report published earlier this year called for "clear central guidance" for police forces on how to deal with the harassment of MPs - and for a greater recognition of the "threat to our democracy posed by" offences committed against them.
