Labour of love... baby Miliband unveiled
Labour Leader Ed Miliband and Justine Thornton proudly show off their new son, Samuel Miliband.
The 8lb 3oz boy was given the name in honour of Mr Miliband's paternal grandfather. He will also have the middle names Stewart, after Ms Thornton's father, and Thornton. The couple's elder son, 18-month-old Daniel, also has the middle name Thornton.
Mr Miliband has expressed embarrassment that he failed to register as Daniel's father. The couple have six weeks to file documents for Samuel.
