Indian Prime Minister Narendra Modi is in the UK to sign a free trade deal expected to lead to a multi-billion pound boost in exports.
UK cars and whisky will be cheaper to export to India and Indian textiles and jewellery cheaper to export to the UK under the agreement, which also commits to a new India-UK plan to tackle illegal migration.
Opponents have warned the deal could undercut British workers due to an extended exemption on national insurance contributions (Nics), from one to three years.
But UK Business Secretary Jonathan Reynolds said this was “completely wrong” and Indian workers on temporary secondment to the UK would get the same deal already offered to many other countries.
