[Q]: Passage: The Finnish and Baltic invasions began a deterioration of relations between the Soviets and Germany. Stalin's invasions were a severe irritant to Berlin, as the intent to accomplish these was not communicated to the Germans beforehand, and prompted concern that Stalin was seeking to form an anti-German bloc. Molotov's reassurances to the Germans, and the Germans' mistrust, intensified. On June 16, as the Soviets invaded Lithuania, but before they had invaded Latvia and Estonia, Ribbentrop instructed his staff "to submit a report as soon as possible as to whether in the Baltic States a tendency to seek support from the Reich can be observed or whether an attempt was made to form a bloc."

[Q]: Passage: In October 2004, Sarah Forsyth claimed that she had been dismissed unfairly by Eton College and had been bullied by senior staff. She also claimed she was instructed to do some of Prince Harry's coursework to enable him to pass AS Art. As evidence, Forsyth provided secretly recorded conversations with both Prince Harry and her Head of Department, Ian Burke. An employment tribunal in July 2005 found that she had been unfairly dismissed and criticised Burke for bullying her and for repeatedly changing his story. It also criticised the school for failing to produce its capability procedures and criticised the Head Master for not reviewing the case independently.
