The crisis in Ukraine continues this week amid a power vacuum, a currency crash and the manoeuvrings and military incursions of its neighbours.
Kiev has requested the attention of the UN security council as Russian forces amass in the largely pro-Moscow and historically Russian region of Crimea.

Also this week: the collapse of the trial of a suspected former IRA killer has led to a judicial inquiry and the near resignation of Northern Ireland's first minister. The suspect – John Downey – was able to produce a letter from the British government that amounted to a "get out of jail free" card dating from the peace talks during Tony Blair's time as prime minister.

The NCCL, it transpires, allowed a group called the Paedophile Information Exchange to gain affiliate status. Several of its members were later convicted of sex offences. Has the row done lasting damage to Labour?
