The number of enforced returns from the UK by year and country of destination is published in table rt_05q (returns data tables, volume 5) in ‘Immigration Statistics, year ending March 2019’, available from the GOV.uk website at:
The term 'deportations' refers to a legally-defined subset of returns which are enforced either following a criminal conviction or when it is judged that a person’s removal from the UK is conducive to the public good. Information on those deported is not separately available and therefore the published statistics refer to all enforced returns. Information for April to June 2019 will be published on 22 August 2019.
The information requested on Venezuelan nationals in same-sex marriage that have been deported to Venezuela is not available in a reportable format.
