State of emergency - Andy McNab

On a freezing winter's night, a small craft skims across the Thames towards London's most exclusive new riverside hotel. On board is a lone assassin, his target - Britain's most powerful new politician.
In a nation threatened by extremist jihadis and torn apart by civil unrest, billionaire businessman Vernon Rolt's plans for a zero-tolerance crackdown on ethnic violence has touched a popular nerve. But his move into politics has made him some deadly enemies.

MI5 operative Tom Buckingham is undercover inside Rolt's organisation. From here he must neutralise the rogue assassins for whom he also has become a target, and discover the deadly intentions of Rolt's new financier, a shadowy Crimean oligarch. But all too soon, Tom gets caught up in a far more devastating plot which will change the political landscape of Europe - for ever . . .
