There are 3.3 million muslims in the UK.
That’s less than the number of muslims in the USA, which is 3.45 million.
Of course in the UK that is 4.4% of the population.
However 1.3 % of the UK population is Hindu, another 0.7% are Sikh and 0.5% are Buddhists.
Also worth noting that Muslims are well represented in government leadership in the UK.
