Sir Malcolm Rifkind has defended Gavin Williamson in an interview with Julia Hartley-Brewer, after the defence secretary urged Philip Hammond to pump more cash into the armed forces.
Rifkind, who himself held the defence brief in John Major's government, told talkRADIO: "Quite rightly, we insist on our military having the best kit, state of the art artillery and it's hugely expensive."
The Tory grandee added that Britain must make sure it provides for "tomorrow's problems" and this is why we need to invest in the military.
"We are a country that depends on trade," Rifkind said, "and that means that we must protect the ceilings. You have to have a very strong royal navy.
"The new defence secretary appears to recognise to importance of a strong defence and is prepared to do what he actually can to achieve it."
