I’m going to say something now that is going to ruin the series Litvinenko for you, rendering it essentially unwatchable, so be forewarned. I’ll do a few sentences for you now so you can really make your mind up. Do you think you, or anyone you love, might want to watch Litvinenko (Thursday 15 December, ITVX)? Then I would suggest you abort this whimsical weekly column right now. The thing I’m going to say about Litvinenko that will ruin it will take up the entire second paragraph and once you read it – once you absorb all the truth inherent to it – you will not be able to enjoy the series Litvinenko, even for one second. Do you understand that? Do you? Are you sure? All right, fine:

David Tennant isn’t doing a Russian accent in Litvinenko. He is just doing José Mourinho’s voice.
