Plaid Cymru is leading with more than half of areas in Wales declared as a new voting system is used for the first time. Reform is in second place.

Welsh Labour has suffered significant losses and is currently third, ahead of the Conservatives, with the Greens taking one seat so far.

This year the Senedd is expanding from 60 to 96 seats and the boundaries have changed too.

The old constituencies and regions have been replaced with 16 new constituencies, each electing six members using a system of proportional representation.

Labour held half of the seats after the last election in 2021.

With almost half of the seats at Holyrood declared, the SNP is by far the largest party in the Parliament – although its vote share is down on the 2021 election.

The Liberal Democrats and Conservatives are tied as the second largest parties. The Liberal Democrats' vote share has risen, while the Conservatives' has fallen.

Despite picking up about 20% of votes across the country, Scottish Labour has not won many constituency seats. The Green Party's vote share has been far lower but more concentrated, translating better into seats.

The largest party at Holyrood before the election was the Scottish National Party led by John Swinney who has retained his Perthshire North seat.

Labour has lost control of 12 councils, most of them going to no overall control.

Reform UK gained Suffolk, Essex, Havering and Newcastle-under-Lyme and more than 600 councillors across the country.

The Liberal Democrats and the Green Party of England and Wales have seen an overall gain in council seats, while the Conservatives have lost over 270.

There were more than 5,000 councillors up for election across 136 councils in England on Thursday, standing for a mixture of district, metropolitan, unitary and county councils as well as all London boroughs.

Labour were defending the most seats with more than 2,500, the Conservatives over 1,300, the Lib Dems just under 700 and the Greens just under 150.

Most of the seats were last contested in 2022, at a time when Reform UK stood in very few areas. That means it stood to gain the most of all the parties.
