If necessary, it is possible to introduce a appropriation law or a short financial law which, during the wash period, passes through all its legislative steps in both houses of Parliament. In rare cases, there may also be time for members of the legislation who have almost completed the legislative process. A washing period is not mandatory: the Prime Minister can obtain the sovereign`s permission to dissolve Parliament immediately, in which case all remaining parliamentary affairs are lost. The last time an election was called without washing time was in 1924, when Parliament was immediately dissolved on 9 October and the legislative elections were held 20 days later. In 2001, Parliament was dissolved six days after the dissolution was announced, after Parliament was adjourned without prorogued. In 1997, Parliament was pro-drug four days after the election date was announced, but Parliament was not dissolved until 18 days later. The wash period is the last day that a UK parliament continues to sit after the Prime Minister has announced the date of dissolution of Parliament, so that general elections can be held, but before Parliament is formally postponed, prorogued or dissolved. During the wash phase, the government tries to do business unfinished and with sufficient multi-party support. This may mean that certain aspects of the economy are compromised to ensure that they can be completed and that the opposition and sufficiently large groups of substantive bankers actually have a veto over controversial or unpopular measures. Discussions on the points that advance during the laundry take place between the „usual channels“ – lashes and other government officials and opposition parties. Before the FTPA came into force in 2011, the Prime Minister had the power to announce the date of the legislative elections (subject to a maximum period of five years between the parliamentary elections) and the date of dissolution of Parliament. This meant „washing time“, the last days of a Parliament where unfinished business had to be agreed by both chambers if they were not to be totally lost, was unpredictable. There has been a long history of criticism of the procedures used to ensure the passage of legislation at the end of a Parliament and that, given the limited time, the bills have hardly been thoroughly examined and introduced into the code.
Admittedly, it was hoped that the 2011 FTPA which provided that elections by universal suffrage would normally be held every five years, would provide greater security in the legislative process, although in the run-up to the 2015 dissolution, concerns were expressed about the impact of the 2011 FTPA on the procedure for reviewing the Finance Act (a number of clauses for the Finance Act 2015 had to be postponed following discussions with the opposition. , see legal update, Finance Act 2015 gets royal approval). For more information on the legislative process in the British Parliament and the steps a bill must take in the House of Commons and the House of Lords before becoming law, see the practical note, The legislative process in the United Kingdom and how bills become law. With respect to the current legislative agenda, any bill that has not been approved by the government until Parliament is dissolved is lost, which means that the government needs the cooperation and approval of the opposition to pass legislation that is still being drafted. An agreement could mean that the government would drop controversial parts of some of the legislation in order to obtain the rest through parliamentary oversight. A report, Wash-up: What Happens to Bills Before Parliament is dissolved, published by the House of Lords Library on 21 April 2017 contains a table containing the government laws that are still before Parliament, the phase they reached on 21 April 2017, and the latest timetable for the closing of their remaining parliamentary phases.
