Mhairi Black, of the Scottish National Party, has become the youngest MP elected in the UK for 350 years.

The 20-year-old now represents the constituency of Paisley and Renfrewshire South, outside Glasgow.

The law was changed in 2006, lowering the minimum age of parliamentary candidates from 21 to 18.

In 1667, 13-year-old Christopher Monck, 2nd Duke of Albemarle, took his seat in the House of Commons.

Newsbeat travelled to Mhairi's constituency office in Paisley to meet her just days before the election.
