An investigation has been launched by the government chief whip into reports that a Conservative frontbencher watched pornography on his phone in the Commons chamber.

Female Tory MPs met Chris Heaton-Harris on Monday night to complain about sexism in parliament, with one alleging that a male colleague was watching pornography next to them in the House of Commons.
