Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE region ( region_id number, region_name text, date text, label text, format text, catalogue text )
TABLE: CREATE TABLE party ( party_id number, minister text, took_office text, left_office text, region_id number, party_name text )
TABLE: CREATE TABLE party_events ( event_id number, event_name text, party_id number, member_in_charge_id number )
TABLE: CREATE TABLE member ( member_id number, member_name text, party_id text, in_office text )
