The finance package was previously denominated in US Dollars. Transferring to Sterling reduced future foreign exchange risks for the UK and had no impact on overall cost.

Commonwealth and Development Affairs, what information his Department holds on assistance provided to Russia by (a) China and (b) Iran to resource military action against Ukraine.

Chinese companies continue to provide military and dual-use goods to Russia's military industrial complex. This is enabling Putin's invasion of Ukraine. We have repeatedly urged China to take all measures to investigate and to prevent Chinese companies from supplying Russia's military, including when the Foreign Secretary last spoke with Chinese Foreign Minister Wang Yi on 22 April. To date, the UK has sanctioned 35 China-based entities for supplying Russia's defence industry under the Russia sanctions regulations.Iran has supported Russia through its large-scale supply of drones, munitions, and ballistic missiles. In response to Iran's supply of ballistic missiles, the UK and its partners took actions including terminating our air services agreement with Iran Air and implementing new sanctions.

Commonwealth and Development Affairs, how much bilateral aid he plans to make available to Ukraine in 2025-26.

We are proud of our fast, flexible, and responsive support to Ukrainians living through Russia's invasion. The UK has provided £5 billion of non-military support to Ukraine since the start of the full-scale invasion. The Prime Minister has said in Parliament that we will continue to support Ukraine, including for humanitarian purposes. On 9 May, the Foreign Secretary announced almost £25 million in new funding to support local Ukrainian organisations to protect the most vulnerable who continue to suffer from Russia's ongoing aggression. This forms part of our funding for 2025-2026 - final funding allocation decisions for the current financial year are ongoing and will prioritise support for those most in need.
