1984, following the miners strike, Moore decides to leave comic writing as a form of attack on Thatchers government, his final work being the collected V For Vendetta series. He joins the Labour party the same year.
After campaigning for Labour and writing many acclaimed pieces for various newspapers, he is selected as the Labour Parliamentary candidate for his home town of Northampton. in 1987 He wins the seat with a majority of 1984 - something he mentions in his victory speach as being quite a coincidence.
In 1989 he is appointed to the shadow cabinet as Shadow Home Secretary by Neil Kinnock, a move that stuns a large proportion of the Parliamentary party, however, with his talents for writing and public speaking he makes an immidiate impact, remarking that the then Home Secretary Douglas Hurd seems to be a "frustrated comic book writer, certainly his claims that crime hasd fallen would rank among the great works of fiction this country has seen".
Moore retains his seat with an increased majority in the 1992 elections, and maintains his position in the shadow cabinet as Shadow secretary of Defence. With the resignation of Neil Kinnock, it is rumoured that Moore will stand for the post of leader, however he throws his vote behind John Smith who then goes forward to win and become the new Labour party Leader. Moore is made Shadow cabinet secretary for Communities and Culture, but by 1991 Moore is back in as Shadow Home Secretary, a position he holds until 1994.
With the death of John Smith, Alan Moore is nominated as new leader of the Labour party, also nominated are Tony Blair, John Prescott and Margaret Beckett. In the leadership election, John Prescott withdraws, backing Alan Moore for the leadership. Margaret Beckett is defeated in the first round and in the second round, Alan Moore wins by 5 votes defeating Tony Blair. John Prescott is elected Deputy leader of the labour party.
In 1997, campaigning on an Anti-sleaze ticket, the Labour party take 328 seats in Parliament making them the party with an over all majority, and with it, Alan Moore the new Prime Minister of Great Britain and Nothern Ireland.
