Matthew recently accompanied a group of religious leaders, rabbis and local politicians on a visit to Poland to commemorate the 70th anniversary of the Warsaw Ghetto Uprising.
Speaking in front of the memorial to the dead, Matthew said: "The world must be always vigilant against such atrocities ever happening again. Standing in the very spot where so many people died it is hard to conceive that the Nazis acted so cruelly and brutally for so many years against innocent people. We must never forget and I am attending this anniversary to show that many people have not forgotten and to do so would be to condemn the victims of the Warsaw Uprising to a second injustice."
In addition to attending the ceremony alongside British Government Minister Don Foster MP, Matthew also visited the Jewish Cultural Centre in Warsaw and the Jewish Museum.
The uprising was the largest single Jewish revolt against Nazi persecution as attempts were made to liquidate the Warsaw Ghetto and send the inhabitants to death camps. With few weapons, food or military experience the inhabitants of the ghetto fought back for three weeks until - against overwhelming forces - the remaining inhabitants committed mass suicide.
