Since responding to the question on 2 April 2008, Hansard, column 1061W, we have continued to look for opportunities to develop agreements with countries for the return of their nationals. I recently visited Nigeria as part of continuing negotiations on a bilateral agreement. The agreement with Pakistan was signed on 24 August 2007 and will enter into force immediately instruments of ratification have been exchanged. We expect that this agreement will come into force during the summer. Signature of the agreement with Vietnam is also expected shortly. Negotiations with Ghana continue.
