Washington, Jul 25 (IANS): Former Democratic presidential hopeful Bernie Sanders, in his speech before the party's National Convention starting from Monday, will emphasise the agreements he reached with the Hillary Clinton to make her political programme "the most progressive".

In his convention speech on Monday night, Sanders "will make clear" that Clinton - who will be officially named the party's presidential nominee - is "much better" than the Republican Party's nominee, Donald Trump, on all the main issues, from economy and health care to education and the environment, Sanders' campaign said in a statement on Sunday night.

The Vermont senator will emphasise that the Democratic Party's "most progressive" platform in its history includes agreements he reached with Clinton to drastically increase access to health care and make tuition at public universities free for students from families with incomes below $125,000 per year, EFE news reported citing the statement.

In his convention address, Sanders will also attack the real estate magnate's programme, especially the portions of it referring to financing his campaign and to the environment, two of the issues the senator focused on during the primaries while mounting a lengthy challenge to Clinton's frontrunner status.

Specifically, Sanders will criticise Trump for allying himself with millionaire brothers Charles and David Koch, two of the main donors to the Republican Party, and for adhering closely to the position of the "fossil fuel industry" that climate change is a farce despite almost unanimous scientific consensus that global temperatures are on the rise due to human activity.

He will also send a message to the 13 million voters who supported him in the primaries that they have begun a continuing "revolution" to transform the US.

Sanders will also maintain his commitment to fight for a government based on the principles of economic, social, racial and environmental justice.

Sanders endorsed Clinton on July 12 and - in negotiations with her campaign - managed to get her to include in the party platform issues such as abolishing the death penalty, increasing the federal minimum wage to $15 per hour and expanding the Social Security program by raising taxes on people earning more than $250,000 per year.

Also slated to speak on the first day of the convention is First Lady Michelle Obama.

The Democratic National Convention is slated to take place from Monday to Thursday in Pennsylvania.
