The UK Christian Institute:

A primary school teacher faced disciplinary action because she didn’t want to read to her class from a storybook about gay penguins.

The teacher, who has not been named, works in a school in a London Borough and her case has been told to a committee of MPs looking at the gay marriage Bill.

Another teacher, from Scotland, says he was pressurised to promote gay marriage against his will and it contributed to a breakdown.

The two teachers have remained anonymous because they fear for their careers, but have permitted a lawyer to outline their cases to Parliament.
