MP Jacob Rees-Mogg welcomes sixth child - named Sixtus

Conservative MP Jacob Rees-Mogg has announced the birth of his sixth child - Sixtus Dominic Boniface Christopher.The origin of Mr Rees-Mogg's choice of name for his latest child is likely to promote debate, as baby-name books say it is derived from a Greek name Xystus, meaning "polished", and should not be confused with the Latin name Sextus, meaning sixth.A further four Roman Catholic popes have been called Sixtus, most recently Sixtus V, consecrated in 1567.
