The Scottish Parliament election will see 73 MSPs returned to Holyrood to represent constituencies across the country.
Here, the PA news agency takes a look at some of the battleground seats which could prove crucial in determining the outcome of the election.

Labour’s Jackie Baillie has held the seat of Dumbarton since the Scottish Parliament was established in 1999. But in the 2016 election her majority was cut to just 109 votes, making it the most marginal seat in Scotland. With Nicola Sturgeon hoping to win an overall majority as she pushes for a second independence referendum, this constituency is one the SNP hopes to win. But Labour, whose fortunes appear to have been revived somewhat by new leader Anas Sarwar, will be desperate to hold on to it.
