'Dr David Mackereth reckons that he has treated more than 120,000 people during more than 20 years as an NHS A&E doctor.
As you might expect in a busy ‘Anything and Everything’ department, his patients have come in all shapes and sizes, and from every race and creed.
Young and old, he sees every gender and sexual orientation.
It makes no difference to him whom a broken arm belongs to, he says, and he has never refused to treat a patient.
As an evangelical Christian, he regards himself as a compassionate, caring and highly ethical doctor, but he always keeps his religious beliefs to himself.
‘If I were to impose my Christian views on patients, I would very quickly lose my job,’ he says.
‘My job is to treat their chest infection or sepsis, dress wounds and save lives. I cannot be prejudiced — nor would I want to be.’
So the quiet and unassuming married father-of-four never imagined he would find himself branded a ‘bigot’ by Piers Morgan on live breakfast TV, as he was last week, and fearing that he would never work as a doctor again.
Nor that he would be at the centre of a legal test case over one of society’s most divisive and incendiary issues — transgender rights.
Or, more specifically, the question over whether a doctor should be legally compelled to use the pronoun ‘she’ when addressing someone born a ‘he’ — and vice versa — on request, even if that conflicts with the medic’s religious beliefs.
Last week, Dr Mackereth, 56, told an employment tribunal that he lost his new job in a government department after he said he would refuse to refer to ‘a 6ft tall bearded man’ as ‘madam’.
He claimed he was sacked as a benefits assessor by the Department for Work and Pensions (DWP) over his religious beliefs and that he is the victim of discrimination.
The doctor alleged that during his two-week training he was asked this hypothetical question in June last year, just four days into the job: ‘If you have a man, 6ft tall with a beard, who says he wants to be addressed as “she” and “Mrs”, would you do that?’
When Dr Mackereth, from Dudley in the West Midlands, said his religious conscience would not let him do so, he claims he was dismissed.'
