The 47-year-old beat JLS singer JB Gill, actress Sarah Hadland and former Love Islander Tasha Ghouri to lift the glitterball trophy in Saturday's live final on BBC One.
McCausland, who was the bookmakers' favourite to win, performed three dances with partner Dianne Buswell.
He said his win was for her, "and for everyone out there who's got told they couldn't do something or thought they couldn't do it".
"It just shows with opportunity and support and determination, anything can happen," he added.
As usual, one of the dances in the grand finale was chosen by the judges, one was their own favourite dance from the series, and the other was a show dance.
The judges gave advisory scores but the public made the final decision.
Tens of thousands of new recruits across bricklaying, groundworks and carpentry are needed to get anywhere near the target, they told the BBC.
The Home Builders Federation (HBF), along with the UK's largest housebuilder Barratt Redrow said skills shortages, ageing workers and Brexit were some of the factors behind the shrinking workforce.
The government confirmed there was a "dire shortage" of construction workers but said it was "taking steps to rectify" the problem.
Last week, Prime Minister Sir Keir Starmer repeated the pledge he made soon after taking power to deliver 1.5m new homes in England by 2029.
Secretary general Mark Rutte said Moscow was "preparing for long-term confrontation with Ukraine and with us", describing the current security situation as the worst in his lifetime.
"We are not ready for what is coming our way in four to five years," he said in his first major speech since becoming secretary general in October, urging members to "turbocharge" their defence spending.
His comments come weeks before president-elect Donald Trump takes office, having previously suggested](https://www.bbc.co.uk/news/world-us-canada-68269354)) the US would not protect Nato allies that were failing to spend enough on defence.
If you have the stomach for it, you can climb the narrow crumbling stone spiral staircase to reach the roof of St Nicholas' Church in Rodmersham.
From the top of the Norman church you get a panoramic view of north Kent. Directly below there is an apple orchard, beyond that fields of arable farmland with the occasional house, and in the distance the town of Sittingbourne, silhouettes of Thames Estuary heavy industry visible against the sky.
This is the land where Quinn Estates developers want to build 8,400 homes, new schools and a new road.
"It's an absolutely colossal development, it will have a devastating impact on this area," says Monique Bonney.
She grew up in Rodmersham and after living and working across the world returned to the village. She got married in St Nicholas' Church and has been an independent councillor for the area for 18 years.
Luigi Mangione appeared at an extradition hearing in Pennsylvania where his lawyer, Thomas Dickey, said the 26-year-old would contest being moved to New York to face murder charges. "I haven't seen any evidence that he's the shooter," he said.
Wearing an orange jumpsuit, Mr Mangione tried to address reporters as he arrived for the hearing. He was heard shouting "completely unjust" and "insult to the intelligence of the American people" before he was bundled into court by officers.
He was arrested on Monday after he was spotted at a Pennsylvania McDonald's following a days-long manhunt that spanned several states. He was allegedly found with a gun similar to the murder weapon, a silencer and a fake ID.
Mr Mangione was denied bail for a second time on Tuesday after prosecutors said he was too dangerous to be released.
Back then, the city was in the grip of war. Intense violence, which followed President Bashar al-Assad's brutal crackdown on pro-democracy protests, engulfed the capital. At any moment you could be shot dead on the streets.
I reported for the BBC from inside Syria on the very first protests in 2011. I reported on the "day of rage",](https://www.bbc.co.uk/news/world-middle-east-12794882),) then on shootings, killings, disappearances, air strikes and barrel bombs - until I myself became numb and lost hope.
I was arrested several times. The regime limited my movements and threatened me, and in 2013 I had to leave.
Over the past decade, I've lived through a rollercoaster of hope and despair, watching my country ripped apart from abroad. Death, destruction, detention. Millions fleeing and becoming refugees.
Like many Syrians, I felt as though the world had forgotten about our country. There was no light at the end of the tunnel.
The Syrian civil defence group known as the White Helmets says it is investigating reports from survivors of the country's notorious Saydnaya prison that people are being detained in hidden underground cells.
Writing on X, the group says it has deployed five "specialised emergency teams" to the prison, who are being helped by a guide familiar with the prison's layout.
Saydnaya is one of the prisons to have been liberated as rebels took control of the country.
Authorities in Damascus province reported that efforts were continuing to free prisoners, some of whom were "almost choking to death" from lack of ventilation.
The Damascus Countryside Governorate has appealed on social media to former soldiers and prison workers in the Assad regime to provide the rebel forces with the codes to electronic underground doors.
In several suburbs, symbols of the power of the Assad dynasty have been torn down or toppled.
The interior ministry says it's creating a ring of steel around the capital. But government forces have notably failed to provide any such defence in cities, towns and villages that have fallen to rebel factions across the country.
Rumours are swirling over the whereabouts of President Bashar al-Assad, with people logging flights in and out of Damascus to work out whether he might have left.
His office has denied all such reports, saying he's still at work in Damascus, but there has been no sign of him.
Syria has remained a divided country, with the deep scars of the years of civil war unhealed, despite the apparent stalemate and status quo that had been in place for around four years until just a week-and-a-half ago.
The embattled leader is facing potential impeachment following Tuesday night's declaration, which was quickly overturned in the National Assembly.
In response to the president's address, the leader of his ruling People Power Party (PPP) told reporters that it had become impossible for Yoon to continue his normal duty.
"His early resignation is inevitable," said Han Dong-hoon.
"I am very sorry and would like to sincerely apologise to the people who were shocked," Yoon said in his brief televised speech.
It had been speculated that he would use the address to the nation - his first since declaring martial law - to resign but he did not do so, instead saying that he would delegate the work of stabilising the situation to his ruling party.
In a 10-minute address to the nation on Thursday, he rejected opposition pressure to stand down, vowing to stay in his post "fully, until the end of the mandate" in 2027.
He thanked Barnier for his dedication during his brief term as prime minister, and accused the French far right and hard left of collaborating in an "anti-republican front" to bring down the government.
French MPs voted overwhelmingly to remove Barnier on Wednesday, just three months after he was appointed by Macron.
The vote was the first time a French government had been voted down by parliament in more than 60 years, a move Macron labelled "unprecedented".
