Natasha - who has two children, Arlo, two, and Angelica, 15 months - will take up the role until Nina returns to her position as anchor in early 2012. Faye Nickolds, editor of 'ITV London Tonight', added: "Natasha has an impressive background presenting national and regional news programmes - including a short spell on 'ITV London Tonight'.
"We're very much looking forward to her joining the team until Nina's return early next year."
