Michel Platini has been described as a "product of the system" by one his fellow Fifa presidency candidates.
Chung Mong-Joon, a former Fifa vice-president from South Korea, confirmed he would challenge for football's top job last week.
A long-time critic of outgoing president Sepp Blatter, Chung has called for a non-European to be elected president.
He told BBC's World Football programme: "It will be very difficult for Mr Platini to have any meaningful reforms. Mr Platini enjoys institutional support from the current structure of Fifa. Mr Platini is very much a product of the current system.
"It is time that Fifa had a non-European leadership. Fifa became a closed organisation for President Blatter, his associates and his cronies and I want to change that.
"If I get elected, my job is not to enjoy the luxury of the office. My job is to change it."
Verification of whether part of MH370 has washed up on Reunion island in the Indian Ocean is expected within days.
Aviation experts believe the two-metre long debris is part of a plane wing known as a flaperon. It appears fairly intact and has no visible burn marks or signs of impact.
Malaysia's deputy transport minister Abdul Aziz Kaprawi said it would take "about two days" to confirm if it was from MH370.
There have been four serious accidents involving Boeing 777s in the 20 years since the widebody jet came into service.
Only MH370 is thought to have crashed south of the equator.
The row about high energy prices has been ignited after British Gas announced its profits had doubled in the first half of this year.
It comes as its parent group Centrica said it would be axing 4,000 jobs, not all of which will be in the UK.
The cut follows a strategic review aimed at delivering savings of £750 million a year by 2020.
British Gas profits were £528 million for the first half of the year, more than it made in the whole of 2014, even though it recently cut prices by 5%.
Which? executive director Richard Lloyd said: "While it's good to see the new commitment from Centrica to focus on serving customers, with British Gas profits high and wholesale prices low, customers will no doubt wonder why cuts to their bills haven't gone further, and haven't included electricity.
"Following the Competition and Markets Authority's blistering assessment of this sector, we expect big suppliers to pass on falling costs to their customers quickly and fairly."
Profits at engine maker Rolls-Royce slumped by almost a third in the first half of 2015, dropping more than £200 million since the same time last year.
Underlying profit before tax was £439m, down from from £646m at this point in 2014 - a drop of 32 per cent - while revenue fell from £6.5bn to £6.3bn, a three per cent fall.
Earlier this month, Rolls-Royce issued its third profit warning in a year, citing weak demand for its aircraft engines.
But despite the latest fall, chief executive Warren East said the company was still on track to hit its 2015 full-year guidance.
An 'ethical hunting' supporter has said "culling" is an important part of conservation work - but condemned those behind the killing of popular Zimbabwean lion Cecil.
Former Zimbabwe game guide Garth Hovell told ITV's Good Morning Britain that while African nations remained too poor to pay for culls themselves, trophy hunters would continue to wield power - and if people have concerns, he added, they need to "step up" and contribute financially.
US dentist Walter James Palmer paid $50,000 (£32,000) to kill the lion, which it later emerged had been lured from the protection of Hwenge National Park before being injured with a bow and arrow. He was shot dead with a rifle 40 hours later.
Mr Hovell said that culling was needed to prevent the spread of disease and to control populations, but said he had grave concerns about some of the practices being employed.
If the hundreds of thousands of people who have signed anti-hunting petitions even donated just $1 (64p) each, they could make a real difference.
Professional hunter Theo Bronkhorst has been charged with organising the hunt, while game park owner Honest Ndlovu may also face charges.
One man hoping to reach Britain from Calais explained that he wanted to go there because "there is no one living in the street" in England.
Nine people have been killed attempting to cross the Channel in the last month, according to Eurotunnel.
More migrants attempted to reach Britain from Calais via the Channel Tunnel on Wednesday night, a day after a man was crushed to death under a truck.
Hundreds of migrants, some seemingly as young as 13 or 14, gathered for a third night along the fence to the freight terminal at Coquelles.
Around 15 were seen climbing through a hole in the wire before using clothes to help them jump over the first of two fences.
French police arrived in riot vans and rounded up some of the migrants, while three or four ran towards parked lorries.
The debris washed up on Reunion island in the Indian Ocean is "almost certainly" from a Boeing 777 - the same type of plane as doomed flight MH370.
Malaysia's deputy transport minister said his chief investigator had confirmed this.
No trace has been found of the Malaysian Airlines Flight since it disappeared in March last year carrying 239 people.
