For the history of the pre-1975 county, see Midlothian (historic).
Midlothian County Council was abolished in 1975 under the Local Government (Scotland) Act 1973, which abolished Scotland's counties and burghs as administrative areas and created a new two-tier system of upper-tier regions and lower-tier districts. Most of Midlothian's territory went to a new district called Midlothian within the Lothian region. The Midlothian district was smaller than the area of the pre-1975 county, parts of which went to other districts:12 Currie, Balerno, Ratho and Newbridge to the city of Edinburgh; Musselburgh burgh and parish of Inveresk (which included the villages of Inveresk, Wallyford and Whitecraig) to East Lothian; East Calder, Mid Calder and West Calder) and the Midlothian part of Livingston to West Lothian; Heriot and Stow parishes to the Ettrick and Lauderdale district of the Borders region.
The boundaries of the historic county of Midlothian, including the city of Edinburgh, are still used for some limited official purposes connected with land registration, being a registration county.3 The Midlothian lieutenancy area corresponds to the current council area rather than the historic county.4 The last lord-lieutenant of the county of Midlothian was made lord-lieutenant for the new district of Midlothian when the reforms came into effect in 1975.5 The former county council's headquarters in Edinburgh became the offices of the new Lothian Regional Council, whilst the Midlothian District Council established its headquarters in Dalkeith.6
In 1991 the council built itself a new headquarters called Midlothian House at 40-46 Buccleuch Street in Dalkeith.7
The Lothian region was abolished in 1996. The four districts in the region, including Midlothian, became unitary council areas.8 The reconstituted Midlothian Council continues to be based at Midlothian House in Dalkeith.
There is a Midlothian constituency of the House of Commons.
There was a Midlothian constituency of the Scottish Parliament up to the 2011 elections when it was divided between Midlothian North and Musselburgh and Midlothian South, Tweeddale and Lauderdale.
The Midlothian council area contains the towns of Dalkeith, Bonnyrigg and Penicuik, as well as a portion of the Pentland Hills Regional Park, Rosslyn Chapel and Dalkeith Palace.
