LONDON, England (CNN) -- The disabled young son of UK opposition leader David Cameron has died, UK media have reported.

Ivan Cameron, six, passed away early Wednesday, the UK's Press Association reported a Conservative Party spokesman as saying.

"It is with great sadness that David and Samantha Cameron must confirm the death of their six-year-old son Ivan," the spokesman said according to the agency.

The spokesman said that Ivan, who suffered from cerebral palsy and severe epilepsy, was taken ill overnight and died at St Mary's Hospital, Paddington, central London early Wednesday morning.

"David and Samantha would ask that their privacy is respected at this terribly difficult time," the spokesman added.

Frank Lampard has insisted that it was Claudio Ranieri who laid the foundations to make Chelsea a leading European light.

Ranieri guided Chelsea to their first Champions League semi-final in his last season at Stamford Bridge and his Juventus side will provide formidable opposition when he returns to west London for their last-16 clash on Wednesday night.

Chelsea face Juventus for the first time in the competition at Stamford Bridge and although Ranieri was sacked by new owner Roman Abramovich in 2004, Lampard still has great affection for the man who signed him from West Ham for £11million.

Lampard was among a host of players signed by Ranieri including William Gallas, Emmanuel Petit, Damien Duff, Wayne Bridge, Joe Cole, Scott Parker, Glen Johnson, Hernan Crespo, Sebastian Veron and Claude Makelele.

"He should take credit," said Lampard. "He brought a lot of important players to the team.

"He signed good players even before the Roman Abramovich era. He elevated John Terry to captain and he's become one of the best in the world since.

"A lot of things have happened at this club, and Claudio is part of that history.

"He took Chelsea from a side that finished in the top six to one that finished in the top four.

"He should take credit for what he did in his time here. I'm looking forward to seeing him again very much. I don't think I would be sitting here if hadn't been for him.

"He spent £11m on me, which seemed a lot of money at the time. He's a great man as well as a great manager.

"I saw that as soon as I met him. He helped me develop from a West Ham player who maybe hadn't seen the real world in footballing terms, and he opened my eyes to things.

"I don't think Ranieri's going to be thinking about proving points. He'll be thinking about getting through to the next round of the Champions League, like us.

"Everyone respects the way he carried himself through his time here, particularly in the end. It'll be great to see him again."

Lampard does not believe that Ranieri was badly treated by the club when Abramovich removed him from the managerial hot seat in favour of Jose Mourinho after a season that saw Chelsea finish second - their best placing for 49 years.

The 'Special One' went on to lead Chelsea to their first domestic title for 50 years but failed to reach the final of the Champions League before departing in September 2007.

"I don't think he was harshly treated," said Lampard. "He enjoyed his time at Chelsea very much and saw the transition of the club from a good team who weren't challenging for the title to one that was.

"The fans appreciate him from the way he took the team on and got it performing here.

"Good luck to him. I don't think he's the kind of man who would look back and worry about those kind of things, anyway."

Lampard admits there is a special desire within the Chelsea camp to try and win the Champions League after they came so close last season.

The width of an upright prevented them from beating Manchester United in a dramatic penalty shootout in Moscow last May.

Terry's miss allowed United to go on and win their third European crown and Lampard admits the desire to go one better this season is very much in the ascendancy.

"There's an added incentive because of the manner in which we came so close last year," said Lampard. "You can't but help having that in the back of your mind after what happened.

"You want to go back and actually win it, whether this year or not. But so much can happen. Little moments can go either way on the way to the final, and you need that bit of luck to succeed.

"We're very determined, but after last year of course we want to win the Champions League."

It will be interim coach Guus Hiddink's first home game in charge and Lampard says the Dutchman has made an immediate impression on the squad following their 1-0 win against Aston Villa at the weekend.

"He has had a good impact," added Lampard. "You could see the start of that against Aston Villa. We were fortunate to have a long week training together last week, so we worked very hard in training.

"The lads, to give them credit, worked hard to try and get a fresh start and the right result against Villa. But now we need to carry on. It was only a start.

"Every coach has slightly different ideas, of course, but the one idea they all have is that they want to win. We haven't performed as well as we should this season, particularly in the last few months, and we should have done better."

SRINAGAR, Indian-controlled Kashmir (CNN) -- A bus rolled into the fast-flowing Chenab River in northern India, killing at least 20 people, officials said.

The bus was heading from hilly Bhaberwah to the Jammu region in Indian-administered Kashmir.

"The death toll may go up as the rescue efforts are continuing," said K. Rajendra, inspector general of police in the Jammu region, earlier during recovery efforts.

At that point, 16 passengers were taken to the hospital, some in serious condition, he added.

Juande Ramos refuses to entertain the thought that his long-term future at Real Madrid could depend on tonight's game.

Ramos has enjoyed an almost perfect start to life since replacing Bernd Schuster in the Bernabeu hotseat in December, winning 10 of his first 11 games and helping the Spanish giants trim Barcelona's lead at the Primera Liga summit back from 12 points to seven.

However, Ramos was only handed an initial six-month contract when he took over the reins and it remains to be seen what the former Tottenham and Sevilla coach must do to earn an extended tenure, especially with presidential elections scheduled at Madrid for this summer.

One school of thought is that Ramos must win a trophy to stay in the post, and with Barca still enjoying a sizeable lead at the top of La Liga and Madrid already out of the Copa del Rey, it appears that the Champions League is the club's best bet of picking up some silverware this season.

That has provided yet another subplot to the clash against fellow European superpowers Liverpool, but Ramos insists he is not thinking about what the tie will mean for his own career, only on helping Madrid get beyond the last 16 stage for the first time since 2004.

"The only thing I'm interested in is getting through the tie because that's the only important thing for Real Madrid," he said.

"It's an attractive tie against a tough team. It's been a few years since Madrid got past this round and this is the only incentive for us.

"My personal situation is not important, I'm only thinking of getting through."

Ramos also preferred not to comment on how drastically things have changed for him over the last few months.

He parted company with previous club Spurs last October after presiding over the worst ever start to a league season in the club's history, with just just two points picked up from their opening eight Premier League games.

However, since taking over at Madrid he has managed to turn the reigning Primera Liga champions from a team in crisis to one of the most in-form teams in Europe.

In the same period of time that Ramos has been at the Bernabeu, his successor at Spurs Harry Redknapp has managed only two wins in 10 Barclays Premier League matches.

Ramos said: "I don't have to prove my reputation as a coach, I've been a coach for many years and everybody knows about me.

"I'm proud of our good run because it's been very good for Real Madrid. I don't have anything to say about Tottenham."
