Baroness Warsi has said in an interview that a Government minister has talked to her about resigning in protest over policy toward Israel and Hamas.
In an interview with Channel 4 News, the former Home Office minister added that there was "unease" on the backbenches over the Gaza conflict and said that one "senior Conservative" backencher had been "on the phone in tears".
She said she hoped her resignation would leave "people who feel the same as I do feel prepared to raise those voices within Government".
