MPs have reported more than 480 people over immigration concerns to a Home Office hotline in the past two years, it has been revealed.
The Home Office confirmed it had received scores of tip offs from parliamentarians between 2014 and 2016 after freedom of information requests from Politics.co.uk.
The news prompted questions over whether MPs could be sharing information about constituents who may have asked for help over their immigration status.
The Green Party said the figures pointed to a “fundamental betrayal of trust” between MPs and their constituents.
A Home Office spokesperson said: “Like any member of the public, MPs can use the form on GOV.UK to report an immigration crime.
“They would only be identified as an MP if they declared themselves on the form, which allows someone remain anonymous.”
