Brits travelling to Spain could face fines of up to £1,000 if they break quarantine rules.
Any Brits returning from Spain can be penalised if they fail to self-isolate for a fortnight, the Manchester Evening News reports.
The Government last night announced that people entering the country from Spain will have to quarantine, following a spike in coronavirus cases in the country.
The Foreign Office has also warned against all but essential travel to Spain, although this does not apply to the Canary or Balearic islands.
Quarantine measures will apply to those returning from mainland Spain, the Canary Islands (Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, El Hierro and La Graciosa) and the Balearic Islands, such as Mallorca and Ibiza, the Department for Transport confirmed.
Authorities in Spain warned the country that lost 28,000 lives before getting its outbreak under control could be facing the start of a second major outbreak, reports PA.

On Thursday, the Spanish health ministry reported 971 new daily infections, the biggest daily increase since Spain’s lockdown ended.
Catalonia became the latest region to crack down on nightlife, trying to halt new infection clusters.
The wealthy north-east region – home to Barcelona – ordered all nightclubs to close for 15 days and put a midnight curfew on bars in the greater Barcelona area and other towns around Lleida that have become contagion hot zones.
The quarantine imposition came as PHE, which was involved in the Spain decision, found itself under-fire from senior Tories for its failure to own up to leadership mistakes during the handling of the pandemic, according to a Sunday Telegraph report.
The paper claimed the Government was considering a “radical overhaul” of the health body after chief executive Duncan Selbie, during an appearance in front of PHE’s advisory board last week, was said to have defended the decision to stop contact tracing during the Covid-19 peak.
