LIVE: Nick Clegg speech on immigration

Nick Clegg is making his first speech on immigration as deputy prime minister, and is expected to call for a bail-like system of security bonds to tackle abuse of immigration visas.

Mr Clegg will say applicants from "high risk" countries would pay cash guarantees to be repaid when they leave.

He has asked the Home Office to pilot the idea.
