Williams vs. Long Williams then scored a points win over Keith Long. As this was Williams' third defence of the British title, he won the Lonsdale belt outright, before dropping out of a fight in America with hard hitting South African southpaw Corrie Sanders, because it coincided with Ramadan.

WBC and The Ring heavyweight title challenge Williams vs. Klitschko

In December he finally challenged for a world heavyweight title, but Vitali Klitschko proved too much, as Williams was stopped in the 8th round after going down four times.

Williams vs. Skelton Williams retained the Commonwealth title with a controversial points win over undefeated Matt Skelton in March 2006.

Second reign as British champion Williams vs. Gammer In March 2007 Williams regained the British title in Wales with a 9th-round knockout of Scott Gammer. Williams came in at the lightest he had been since his pro debut 16 stone 4 pounds (4 stones lighter than his previous fight), after training himself for the fight just with a piece of paper that contained a conditioning programme given to him by Joe Dunbar who had worked with Lennox Lewis.

Williams vs. Platov After he had watched the tape of his fight with Gammer, Williams decided he would continue boxing and took a fight with Ukrainian prospect Oleg Platov (26–1, 22 KOs). He came in again at 270 lbs. Both fighters were engaged in wild exchanges from the first bell on. The Ukrainian picked up a badly-bleeding cut above the left eye following an accidental headbutt in the second round and he continued to swing wild punches but not without taking some huge shots from Williams. After 2:15 in the fourth and with the cut getting worse, the referee waved the fight off. According to the rules of the IBF, it was declared a no contest. Sauerland managing director Chris Meyer defended the decision. "The rules are clear", he said. "We had an accidental headbutt and the referee, who consulted the doctor several times, ruled he could not continue to protect his health." Speaking exclusively to SecondsOut after the fight a disappointed Williams said: "He (Platov) was looking for a way out and he got it. He knew the rules and worked them. He was starting to tire and knew it was only a matter of time before I knocked him out. ...I found it slow in the early rounds but I when I got going I started to get on top. He knew I was gonna knock him out and he was looking for a way out. I’m not sure whether or not it was a punch or a head clash that cut him in the second round. It took be a little while to get going but I really enjoyed it, it was a great fight while it lasted. But he was looking for a way out. He kept falling to the floor and it was only a matter of time before I knocked him out."

Williams vs. Airich On 30 May 2008 Williams defeated unbeaten German, Konstantin Airich in a highly controversial fight. Williams had a total of 3 points deducted in rounds 2 and 5 creating a feeling afterwards that the referee was blatantly on the side of the German. In addition he was given 2 standing 8 counts by the referee in round 3 despite not actually being knocked down or touching the canvas, and was also counted after slipping in round 4.Williams-Airich Video: Watch an amazing heavyweight battle as Danny Williams takes on Konstantin Airich, the referee and others! . Eastsideboxing.com (30 May 2008). Retrieved on 7 March 2013. After managing to fight back and score a knockdown himself in round 5, in the 6th round Williams unleashed a series of extremely punishing blows on his opponent sending him reeling across the ring. At this point Airich's promoter Ahmet Oner controversially ran over and rang the timekeeper's bell himself to end the round and save his fighter, even though there was still 1:28 left to go in the round. Despite this confusion the fight continued after the shortened 6th round and after seeing his man absorb more heavy punishment in the next round Oner eventually threw in the towel handing Williams a 7th-round TKO victory.

In the aftermath of the fight Williams was extremely critical of the performance of both the referee and fight promoters, and called for the British Boxing Board of Control to conduct an immediate investigation into the fight.Williams to lodge fight complaint.
