As a proud Londoner and Englishman all i can say is that us British will stay resolute through anything a few crazy terrorists can come up with whether they're so called 'British citizens' (which i think is an insult to call them, they are nothing but scummy traitors and anyone who shares they're ideology in this country should be tried for treason)
Remember Stamford Bridge, Agincourt, The Spanish Armada, Napoleon and Hitler..... We shall never be defeated!!!
