David Tennant’s tribute to Lis Sladen

I just can’t believe that Lis is gone. She seemed invincible. The same woman who enchanted my childhood, enchanted my time on Doctor Who and enchanted generations who have watched her and fallen in love with her – just like I did. I feel very honoured to have shared a TARDIS with Sarah Jane Smith, and I feel very lucky to have shared some time with Lis Sladen. She was extraordinary.
