Kelly, who is still just 36 was elected in 1997 and quickly established herself into her ministerial career, and remarkably has continued her unprecedented rise whilst bringing up her four young children.
Newspapers have described Kelly as a "devout in faith" Christian, and respect has been given to her from all corners of the political arena. Her background is as a Northern Irish Catholic, and she moved with her family to Ireland and then onto England.
The new Education Secretary has fiercely opposed the House of Commons proposals for embryonic stem sell research, and has said that she would feel uncomfortable if given a ministerial position that dealt with abortions, the morning-after pill or contraception in the developing world.
She has openly admitted that Christianity in her life is vital, although she has commented that her faith will remain a private matter.
Recently she reported to the press, "I am a practicing Catholic. These are not issues I have discussed with anybody but clearly I have strong personal principles. I would have to abide by them in my political career if they are strong personal principles."
Church groups have backed Kelly throughout her career, and she has been involved with church groups such as Church Action on Poverty in backing their "Debt on Our Doorstep" campaign. She said at that time that faith groups could play a key role in addressing these type of matters.
Statistical analysis and precision to details have allowed Kelly to comprehensively outwit many other politicians during debates, and has allowed her to impress Prime Minister Tony Blair to rise in the Labour Party hierarchy.
Kelly received a comprehensive education, studying at Westminster School, Oxford University and then at LSE. But despite this grand rise to her new role, some sceptics are suggesting that she may now struggle to juggle around her political requirements to visit schools and universities whilst attempting to get home to give her own children their share of attention.
As the latest Christian MP to enter the Cabinet, all eyes are now on Ms Kelly to promote the Christian principles firmly as a guiding hand in the political arena, and to be the voice of Christians across the country.
