Tablighi Jamaat already has a temporary mosque for 2,500 worshippers on the site, a former chemical works, which it has owned since 1996. It originally produced plans for a new mosque with a capacity of 40,000, but scaled them back under a wave of protest. In 2013 the High Court ordered the sect to close the temporary mosque because it did not have planning permission. It has so far refused to do so.
