The Defence Secretary has confirmed that the Royal Marines bases at Chivenor and Norton Manor will not be closing.
It follows months of speculation that the sites were due to be shut in favour of creating a new super-base in Plymouth.
40 Commando's future in Taunton is safe, three years after it was earmarked for closure by 2028.
The Ministry of Defence no longer intends to get rid of Norton Manor Camp following recent assessment work carried out by the Defence Estate Optimisation Programme.
In a statement to the House of Commons today, Defence Minister Tobias Elwood will announce that the future of 40 Commando at the Norton Manor base in Taunton is secure and the site will be retained for ongoing defence use. The MP for Taunton Deane, Rebecca Pow, believes that seeing the site for himself during a visit earlier this month, helped the Defence Secretary make his decision.
