What are we to make of the announcement that Boris Johnson is to become a father again this summer – the baby’s mother being Carrie Symonds, formerly described as his girlfriend, now his fiancée? Is the Prime Minister’s private life any of our business? Mr Johnson has never presented himself as a model of moral rectitude. So, since he doesn’t claim a moral position, perhaps there is none to be attributed to him. Nevertheless, the chroniclers of public life frequently note that Boris has been commonly described as a “philanderer”. He has been married twice before, and social media often features jokes about the uncertain number of children he has fathered in his Wikipedia entry – “five or six”. But even if his private life is none of our business, it will still be – in the history books – a matter of record, because he is the head of government and surely a historically significant figure. Moreover, Boris and Carrie are setting another record: he will be the first prime minister for 200 years to marry while at 10 Downing Street. And the first British PM to be married to a pregnant bride. The photographers will be keen to acquire the wedding snaps for that occasion. Eagle-eyed gossip reporters will be watching to see if his children from previous relationships will be present. It is noticeable that while Boris is often publicly supported by his father, Stanley, his sister Rachel, and his brothers Jo and Max, his offspring from his marriage to Marina Wheeler are seldom in evidence. Some have spoken critically about him. His eldest daughter has described him as “selfish” – in vehement terms too. If there were a strong “family values lobby” in Britain, as there has been in America, it might indeed consider “Boris the Philanderer” as a less than edifying model for marriage and family life. More liberal divorce laws are likely to be enacted if those at the top take a lighter approach to the dissolution of marriage. Yet all social studies stress that children benefit from a stable family life and the presence of two parents. Christians are supposed to be restrained in making moral judgments about others – “judge not, that ye be not judged”, and advised to look at our own faults rather than the failings in others. Perhaps Boris provides us with such an opportunity. But there are quite a few secular commentators expressing the hope that, at the age of 56 in June, this Don Juan may finally settle down.
