Local MP Alan Mak has been officially sworn in during a Parliamentary tradition that dates back to the 17th century.
He took the Oath of Allegiance to His Majesty The King, a declaration of loyalty to the state, using the King James Bible.
Members of Parliament can either swear in using a religious text or take a non-religious, solemn affirmation.
They are required by law to do this before taking their seats in Parliament after a General Election.
MPs take the oath by holding the sacred text in their uplifted hand and saying the words of the oath: I swear by Almighty God that I will be faithful and bear true allegiance to His Majesty King Charles, his heirs and successors, according to law. So help me God.
MPs cannot sit in Parliament, speak in debates, vote or receive a salary until taking the oath or affirmation.
After taking the oath, MPs then sign the 'Test Roll'. This is a parchment book kept by the Clerk of the House of Commons.
Finally, MPs are introduced to the Commons Speaker by the Clerk of the House.
Mr Mak, who was re-elected as our local MP for the fourth time in the General Election, said: "It is always a humbling moment when you take the Oath of Allegiance on the floor of the House of Commons, which then allows you to take your seat in the Chamber.
"Once again I feel honoured to have been given the privilege of representing the people of the Havant Constituency and being their strong voice in Parliament."
