According to Erskine May - 'There are opposition parties but only one is regarded as the 'Official Opposition' and that is the largest minority party which is prepared, in the event of the resignation of the government, to assume office.' (Erskine May para 4.6).
The Leader of the Opposition and some of the Leader's principal colleagues in both Houses form a group, known as ‘the Shadow Cabinet’, each member of which is given a particular range of activities on which it is their task to direct criticism of the Government's policy and administration and to outline alternative policies.
