more integrated into our country". He agreed parents should be responsible for making sure children speak English. Cameron also said: "If you look at the figures for the number of people who are brought over as husbands and wives, particularly from the Indian sub-continent, we should be putting in place – and we will be putting in place – tougher rules to make sure they do learn English and so when they come, if they come, they can be more integrated into our country." Also in February 2011, the UK Border Agency was upbraided by an independent Government inspector because immigration staff were failing to take action against hundreds of migrant workers who have no right to stay in Britain. Chief Inspector John Vine reported that the visas of migrants whose jobs had ended were not being cancelled, and found that insufficient checks were being carried out on companies which sponsor overseas workers. In April 2011, Cameron delivered a speech on the government's immigration policy, which sparked a row with coalition partner Liberal Democrat Business Secretary Vince Cable, and which he concluded as follows: "But with us, our borders will be under control and immigration will be at levels our country can manage. No ifs. No buts. That's a promise we made to the British people. And it's a promise we are keeping." It was reported by the Office for National Statistics in August 2013 that the net number of immigrants arriving in Britain was 176,000 in the 12 months to the end of December 2012, up from 153,000 the previous year. In a speech in October 2013, Cameron said that schools must produce young people who are 'fully capable' of doing work in a manufacturing facility, a cap on the number of migrants from outside the EU was part of the government's attempt to substantially reduce levels of net migration, and: In May 2014, the Cameron government passed the Immigration Act 2014. In her May 2014 appearance on the Andrew Marr show, Home Secretary Theresa May blamed the Liberal Democrats coalition partners for the immigration target failure, when it was reported by the Office for National Statistics that the net influx of immigrants had risen to 212,000 in the year to December 2013, from 177,000 the previous year. In November 2014, Home Secretary Theresa May made clear government is preparing for public admission of failure to cut net migration
