The United Kingdom has joined the US is condemning Maduro and accepting Guaidó as the new president. After Maduro refused to declare a new election the UK released the official statement and it was announced by their Foreign Secretary Jeremy Hunt.
Nicolas Maduro has not called Presidential elections within 8 day limit we have set. So UK alongside European allies now recognises @jguaido as interim constitutional president until credible elections can be held. Let’s hope this takes us closer to ending humanitarian crisis— Jeremy Hunt (@Jeremy_Hunt) February 4, 2019
