The Conservative party's Nicola Blackwood has fulfilled her promise to sing live on BBC Oxford radio, after scraping a victory in the Oxford West and Abingdon seat.

The seat, formerly belonging to the Liberal Democrats, was the only seat to change in Oxfordshire - also home to Tory leader David Cameron's constituency.

Earlier in the night, Ms Blackwood had promised she would sing if she won - after fellow Tory MP Ed Vaizey revealed she is a trained opera singer.
