Labour leader Jeremy Corbyn is seeking to woo workers with the promise of four new bank holidays each year.
The policy plans would give people additional days off on each of the national patron saints' days because "our workers deserve a break" said Corbyn.
The extra bank holidays would fall on St David's Day on 1 March, St Patrick's Day on 17 March, St George's Day on 23 April, and St Andrew's Day on 30 November to "unite our four nations".
"For years, Britain's workers haven't had a proper pay rise, with wages for most people still below 2007 levels," Corbyn will say.
"After seven years of painful austerity, our workers deserve a break – and under a Labour government, they will have the opportunity of four more days off a year. The four nations that make up our great country have rarely been more divided due to the damaging and divisive policies of this Conservative government."
With eight bank holidays currently, the UK has the fewest of the G20 countries where the average is 12.

The promise comes with just 46 days until the General Election. Labour is behind in the polls, with a ComRes survey for the Sunday Mirror putting Theresa May's Conservative Party at 50 per cent, ahead of Labour on 25 per cent. In the same survey, 62 per cent said May would make the best Prime Minister, with Corbyn on 25 per cent.
