I didn't say the number of asylum claims had increased, I said net immigration, the asylum backlog and small boat crossings had increased. The numbers we were returning weren't miniscule and reduced massively after 2020.
In 2014 - the backlog of asylum claims was under 20,000 (and had been for years). It started to increase gradually and by 2020 it had more than doubled. By 2023 it was close to 140,000 - a 600% increase. We didn't need asylum hotels until recently!
At the start of 2015 net migration was just over 300,000 a year. It had increased between 1999 and 2003, but had remained relatively stable since. Brexit caused EU migration into Britain and British migration to the EU to fall, but non-EU migration increased right up until the Covid drop off. From 2021 onwards, it sky rocketed month on month to well over 800,000 most of which was due to non-EU migrants, while EU migrants continued to leave.
In 2019, small boat crossings were virtually zero and always had been. After the Tories shut down all other routes to seek asylum in 2020, they skyrocketed month on month before hitting a peak of almost 50,000 in 2022.
Before 2014 over 46,000 people who failed asylum or whose visa expired were returned in a combination of enforced, facilitated voluntary or independent voluntary. Between 2010 an 2014 well over 25,000 a year were returned forcefully or facilitated voluntary. By 2019 (i.e. before Covid) returns had fallen to 20,000. Returns have started to increase again, but are still only at 35k and up until last year, that was mostly due to an increase in voluntary returns. Monitored returns have increased since Labour got in to levels just higher than those in 2010, but enforced returns remain below 10,000 - but should start to increase with the new return deals Starmer has signed.
