Prime Minister Boris Johnson has said "British Muslims are helping to make this country the success it is today", as he delivered an Eid al-Adha message.

Millions of Muslims in the UK are marking the festival, which represents the willingness of Ibrahim, known as Abraham in other traditions, to sacrifice his son for God.

It also comes as Muslims perform the Hajj pilgrimage in Saudi Arabia - a mandatory religious duty that must be carried out at least once in the lifetime of all adult Muslims.

Mr Johnson said: "Whether you're one of Britain's 3.3 million Muslims, or one of more than a billion people worldwide celebrating Eid al-Adha this week, I want to take this opportunity to say Eid Mubarak to you all.

"The story of Eid al-Adha is one of sacrifice, about doing your duty and doing what's right. "And that is something we see daily from Muslims right across the UK - men and women who, in all kinds of different ways, make such a huge contribution to modern British life.

"In business, in our public services, in culture and the media, at the highest levels of government and of course in England's World Cup-winning cricket team, British Muslims are helping to make this country the success it is today.

"And, particularly during Eid but also all year round, we see extraordinary generosity from individuals in their support for charities that help the less fortunate - really living the values of Eid al-Adha.

"So while British Muslims celebrate Eid al-Adha, I think it's only right that the rest of us celebrate the contribution of British Muslims. Eid Mubarak."
