Prince Ali, beaten by Sepp Blatter 133 votes to 73 in the initial race for the Presidency last year before the Swiss surprisingly stood down, believes the under-fire governing body must learn from the scandals of last year, which began when the FBI and Swiss authorities indicted 14 officials and marketing executives in raids in Zurich.

"This is an incredibly important moment for the future of the organisation," he said in London at the announcement of his manifesto.

"It will be a catastrophe for the organisation if things do not go the right way.

"The most important thing is that we have to have a real, responsible leadership in FIFA, no matter what happens in the future, you have to have a leadership that can implement the right changes and that is what I am dedicated to doing."

Prince Ali is up against Bahrain's Asian Football Confederation chief Shaikh Salman Bin Ebrahim Al Khalifa, as well as France's Jérôme Champagne, South Africa's Tokyo Sexwale and UEFA general secretary Gianni Infantino in an election due to be held the FIFA's Extraordinary Congress in Zurich on February 26.

Speaking during a series of meetings around England, Ireland, Scotland and Wales designed to boost his support, he believes he is the only one of the five who can restore FIFA's reputation.

"We don't want the situation where a year or two down the line more scandals come out," he said.

"I am determined to save FIFA and to do it from within.

"There are a lot of people around the world who want to have a strong, solid FIFA and I am one of them."

His manifesto calls for a maximum of two four-year terms - a change on the current lack of limits - for the FIFA President, as well as for the ruling Executive Committee.

He wants a revised bidding process for the World Cup from 2026 onwards, which would be more in line with the International Olympic Committee's system for prospective Olympic host cities.

This could involve banning host city visits and evaluating bids based on the recommendations of professionals.

Transparency has also been highlighted as a priority.

"Regardless of what happened, the main issue is how business is conducted and it has to be open and it has to be accountable," Prince Ali said.

"[This] includes the full disclosure of the salary of the President and the Executive Committee."

His vow to be a "hands-on" President, should he be elected, contrasts to the plans of favoured-rival Shaikh Salman to be a "non-executive" figurehaead.

"You have to be a hands-on President, with a proper chief executive," Prince Ali claimed.

"You do need to have proper leadership and somebody who takes responsibility which we have not seen in the past."
