29 18 December 2020: A gathering in No 10 Downing Street ahead of the Christmas break Extracts from regulations and guidance On 5 November 2020, a second national lockdown was introduced which required people to stay at home and prohibited indoor gatherings of two or more people from other households except for permitted exceptions, including where the ³gathering is reasonabl\ necessar\ « for Zork purposes ́. On 2 December 2020, England was divided into three tiers, with Londo n in Tier 2 in which gatherings of two or more people indoors continued to be prohibited unless an exception applied, such as where the gathering was reasonably necessary for work purposes. Government guidance, issued on 30 November 2020 for the Christmas period, on visiting pubs and restaurants advised: ³although there are exemptions for work purposes, you must not have a work Christmas lunch or party where that is a primarily social activity and is not otherwise permitted by the rules in \our tier. ́ On 1 6 December 2020, London was moved to Tier 3. Indoor gatherings of two or more people from different households continued to be prohibited. Social distancing remained the rule at Zork, Zith offices advised ³to maintain social distancing guidelines (2m, or 1 m with risk mitigation where 2m is not viable), wherever possible, including while arriving at and departing from work, while in Zork and Zhen travelling betZeen sites ́. The Christmas part\ guidance issued on the 30 November 2020 remained unchanged. Summ ary On 18 December 2020 a gathering lasting several hours took place in the No 10 Press Office.

This was known as μWine Time Frida y¶ where bottles of wine were placed on a table in a small room adjacent to the main Press Office and people could help themselves. On Fridays senior officials would routinely recognise the efforts of staff by handing out some awards and a small trophy cup to recognise weekly achievements.
