"I wonder if her son Festus is still in the job she got him earning, something like £50k/pa in parliament?"
Perhaps you have confused this scandal-ridden Labour MP with that of another, Kate Osamor, who continued to employ her Haringey councillor son Ishmael as a parliamentary communications officer following his drug conviction.
She finally stepped down as Shadow Secretary of State for International Development in the same week her mother, Martha (Baroness Osamor of Tottenham in the London Borough of Haringey and of Asaba in the Republic of Nigeria), was elevated to the House of Lords.
