Theresa May: Immigration 'harms social cohesion'
Home Secretary Theresa May has told her party's conference that high levels of immigration make it impossible to have a "cohesive society".
Her comments were supported by David Cameron, who admitted he was frustrated by his government's failure to reduce the level of net migration.
Mrs May's comments were criticised by some business leaders, who called them "irresponsible".
