A collection of portraits of the British and Irish negotiators who agreed The Treaty to end the War of Independence has gone on display at the Irish Embassy in London.

The works, completed between 1921 and 1922, are being exhibited to mark the centenary of the event.

They feature a group of five negotiators and their secretariat from Dáil Éireann - led by Michael Collins and Arthur Griffith - and the political leaders of the British Empire – David Lloyd George, Winston Churchill and Frederick Smith (Lord Birkenhead).

The works are by John Lavery, a much sought-after portrait painter in London whose wife Hazel urged him to carry out to paint them.

Ms Lavery was also an artist whose image appeared on the banknotes of the new Irish State.

Most of the paintings come from The Hugh Lane Gallery in Dublin.

The collection also includes a painting of the House of Lords in London ratifying The Treaty in December 1921, usually on display at the National Gallery of Ireland.

And it features a painting from 1923 of the Viceregal Lodge - now Áras an Uachtaráin - which is housed in the Áras itself.
