UKIP Leader Gerard Batten MEP has petitioned Queen Elizabeth II to prorogue Parliament until after the United Kingdom has left the European Union on 29 March 2019.
Concerned that Members of Parliament are using the current session to attempt to delay or stop Brexit entirely, the UKIP Leader has petitioned Her Majesty to discontinue the current session of Parliament without dissolving it (proroguing).
The UKIP Leader writes:
"It is evident that these same Members of Parliament are attempting by all and any means to thwart this result. They are accordingly in breach of their pledges to you and us, your citizens, and of a long-standing Constitutional convention whereby Parliament must implement the will of the people expressed in a popular vote and are bound by electoral manifestos which have received popular assent at General Elections.
"Therefore, I ask Your Majesty to thwart their efforts and to prorogue Parliament from now until after 29th March 2019 which is the agreed date set aside in the Withdrawal Act of Parliament of 2018 when the United Kingdom will leave the European Union."
Mr Batten also notified Her Majesty that the 1992 Treaty on European Union is treasonous:
"In 1992 the House of Commons passed into Statute the Treaty on European Union. This Treaty and Statute purport to make Your Majesty a 'citizen of the European Union'. The Treaty states that Your Majesty as a 'citizen of the Union' will 'enjoy the rights conferred by this Treaty and shall be subject to the duties imposed thereby'. To presume to convey rights on, or to impose duties on Your Majesty was, and remains, unlawful and treasonous under the Bill of Rights, and the Coronation Oath. Your Majesty's ministers were gravely in error and wrongly advised you."
