The bill was included in the King's Speech at the 2024 State Opening of Parliament.^[4] It was introduced to Parliament on 12 September 2024 and had its second reading on 14 October 2024.^[5] It had its third reading in the Commons on 9 December 2024, and its third reading in the House of Lords on 11 March 2025, and received Royal assent on 3 April 2025.^[6]

Martyn Hett, by whose name the legislation is known, was one of 22 people killed in the bombing, and his mother Figen Murray campaigned for this new law.^[3]

This legislation had previously been included in the king's speech at the 2023 State Opening of Parliament in the previous parliament,^[7] but had not been introduced by the time Parliament was suspended for the 2024 general election.^[8][9] Martyn Hett's mother walked 200 miles to London in May 2024 to meet the prime minister, Rishi Sunak, and reported that he "promised her he would introduce Martyn's Law to Parliament before the summer recess, but could not guarantee it would be passed before the next election"; hours later he called the general election, bringing a halt to parliamentary business.^[10]
