Labour leader Ed Miliband and his partner Justine have called their second child Samuel Miliband, it was announced today.
The 8lb 3oz boy, who was born late Sunday night, was given the name in honour of Ed's paternal grandfather.
He will also have the middle names Stewart, after Justine's father, and Thornton, which is her surname, according to a Labour Party spokesman.
The couple's elder son, 18-month-old Daniel, also has the middle name Thornton.
Mr Miliband has previously expressed embarrassment that he failed to register as Daniel's father on his birth certificate, and said he and Justine will "get round to" marrying at some point.
They have six weeks to file documents relating to Samuel's arrival.
