We must preserve our dearest values

feel scared for their children’s future in the UK and are concerned they may be viewed by some as targets. Britain must take these concerns seriously. I believe we need a zero-tolerance approach to antisemitism and to be clear in saying that nothing can excuse antisemitism in any form.

Ensuring there is visible policing and strong community relations must be part of this and we should constantly be asking what more the Government can do to help build confidence in British Jewish communities.

We also need to ensure that antisemitism and racism are tackled online and that sites such as Facebook enforce their own rules when it comes to hatefilled content on its social network. The shocking online attacks that my colleagues Luciana Berger and Louise Ellman haverecently been subjected to highlight this new danger and there should be no safe haven for antisemites online. That is why Yvette Cooper and I have been calling on social network sites to do more to tackle this insidious threat.

What we saw this weekend in Paris was a demonstration of the defiance and resolve of millions in response to the atrocity of a hate-fuelled few.

With Holocaust Memorial Day approaching on the January 27 in the year of the 70th anniversary of the liberation of Auschwitz and the other death camps, we know that commemoration of past atrocities must be combined with a determination to resist hate and intolerance in our own time. This is a time to redouble our commitment to preserve the values we hold dearest, and resolve to work together to tackle extremism in all its forms.
