For the UK taxman it's not as simple as being out of the country for 183 days in one year. Additionally you may only average a maximum of 90 days over three years, prove that your main domicile is elsewhere AND show that you pay tax there.
If the taxman thinks that your domicile is in the UK (phone bills, mortgage, family, car registered here) they will insist upon you paying UK tax in full, even if you pay some tax elsewhere. If that's the situation then they'll deduct what you pay elsewhere (once you can prove you've paid it) from what they think is due in the UK and then demand the balance.
In short it's no longer sufficient to just say you live, work and pay tax elsewhere. Inland Revenue want you to prove that you do all those things and that you don't have a base here.
Once you're through those hoops it seems you've the russian side to deal with which Pushkin is suggesting won't happen. If they don't want your tax money, great. But the Inland Revenue will.
My best advice is that you get professional advice. Whatever you pay it will be worth it because the IR have long memories and in these cash strapped times are becoming more money grabbing than ever.
