A prominent Muslim leader is to issue a plea to abide by the law in Britain and not press for a separate parliament.
Rafiq Hayat, head of the UK branch of the Ahmadiyya Muslim Community, will tell more than 30,000 followers that respecting the culture of the country they live in is key to their faith.
He will also urge against sending children to Islamic schools.
His remarks will be welcomed by ministers as a sign that Muslims are shunning political separatism. They follow growing concern over the spread of sharia courts.
Mr Hayat is to make his plea at Britain’s biggest annual Islamic convention near Alton, Hants, this weekend.
He will say: “In countries such as the UK, where the laws are just and freedom of faith was enjoined, Muslims have a duty to contribute to the well-being of the society.
“Muslims should not press for the establishment of an alternative authority or so-called Islamic parliament.”
