The UK government has replaced a Palantir software system used to find homes for Ukrainian refugees with an internally-built system, reportedly saving millions of pounds. The original system was provided by Palantir for free for six months, but subsequent contracts were worth £4.5m and £5.5m. The new system is said to be more flexible and meet high standards of security. The change is seen as a step towards more sovereign technology and reducing reliance on external suppliers.
