Damian Green has been appointed work and pensions secretary.
He takes over the position from Stephen Crabb, who resigned from the position earlier today.
The Government will announce an extra £20 million of funding to boost troubled Police Crime Commissioners (PCC) after their difficult first year.
Policing Minister Damian Green is expected to make the announcement in a speech later today at an event for PCCs.
He will say:
Raising the age to which someone can sit on a jury to 75 is about "harnessing" the knowledge and "life experiences" of a generation, said Criminal Justice Minister Damian Green.
Each year, around 178,000 people in England and Wales undertake jury service, but currently only those between 18 and 70 can sit as jurors.
People up to the age of 75 will be able to sit on juries in England and Wales, according to new plans announced by the justice minister.
The proposal to raise the upper age limit of jurors from 70 to 75 is part of a drive to make the criminal justice system more inclusive and to reflect modern society, the Ministry of Justice said.
Volunteer Magistrates "have been with us for 650 years" and are more than capable of dealing with tougher cases than they currently hear, justice minister Damian Green told Daybreak.
Conservative Mr Green defended his proposals to give more responsibility to Magistrates should have "proper work to do, in the 21st century".
Justice minister Damian Green is expected to say that magistrates should focus their time on cases where they make a "real difference" to communities.
More cases should be tried at magistrates courts rather than crown courts, the justice minister will say later today.
In a speech to magistrates, Damian Green is expected to say four in 10 people appearing at crown courts could be sentenced at magistrates court instead.
The speech comes ahead of a public consultation into the role of magistrates, who have limited powers to convict and sentence minor crimes.
Policing minister Damian Green said that a forthcoming review into the use of cautions by the police is intended to ensure serious and repeat criminals end up before a court.
