There is a danger of a racist backlash in Britain aimed against the Muslim population and other ethnic minorities. The day following the bombings the Muslim Council of Britain reported that 30,000 threatening e/mails have been received by Muslim organisations. This threat must be fought against . CWI

Our thoughts are with all those killed and wounded in this morning’s terrible attacks in London. London is a centre of peace, the most multiracial city in Europe and a global centre of opposition to the war and occupation of Iraq and Afghanistan. A majority of those killed and wounded will have opposed the war in Iraq; some will have joined the huge marches for peace. SWP UK

On behalf of Sinn Féin I offer my sincere condolences to the victims and the families of those killed and injured and to the people of London. Gerry Adams/Sinn Fein

With so many Irish people resident in London, there has always been a close affinity between the Irish people and the British capital and all our thoughts will be with those who have been injured or who have lost relatives in these attacks. Pat Rabbite/Labour Party

Indymedia UK stands in solidarity with all the victims of today's horrific attacks in London. We share the disgust felt by all about these acts and their perpetrators, our thoughts are with the victims and their families. We are also acutely aware that these events will be exploited by the most reactionary elements of the British media and political establishment for their own selfish purposes. UK Indymedia

We have worked without rest to remove the causes of such violence from our world. We argued, as did the security services in this country, that the attacks on Afghanistan and Iraq would increase the threat of terrorist attack in Britain. Tragically Londoners have now paid the price of the government ignoring such warnings. George Galloway/Respect
