A Christian doctor lost his job in a government department after he refused to refer to “a six-foot-tall bearded man” as ‘madam’, a tribunal heard.

Dr David Mackereth, 56, claims he was sacked as a disability benefits assessor by the Department of Work and Pensions over his religious beliefs.

The father-of-four alleges he was asked in a conversation with a line manager: “If you have a man six foot tall with a beard who says he wants to be addressed as ‘she’ and ‘Mrs’, would you do that?”

Dr Mackereth, an evangelist who now works as an emergency doctor in Shropshire, claims his contract was then terminated over his refusal to use transgendered pronouns.

He argues that he was dismissed “not because of any realistic concerns over the rights and sensitivities of transgender individuals, but because of my refusal to make an abstract ideological pledge”.
