Andy Murray's Wimbledon preparations included a late night watching the result of the referendum but he refused to divulge whether he is a jubilant leaver or a dismayed remainer.
The world number two takes a keen interest in major political stories and famously came out in favour of Scottish independence on the night of the referendum in 2014.
Murray revealed earlier this week that he would definitely take part in Thursday's European Union vote but said he was still considering which way to go.
He said: "I have followed it very closely. I stayed up pretty late on whatever night it was, into the morning. But, yeah, I'm not discussing that today, unfortunately."
The smile that followed was recognition that his views on such a subject on the eve of Wimbledon would be big news even within the seismic events of the week.
Murray certainly does not want any external distractions as he builds up to the most high-pressure fortnight of his year.
The debate that blew up ahead of the French Open about the reasons for his split from coach Amelie Mauresmo may well have contributed to his struggles in the first two rounds of that tournament.
Murray moved unexpectedly quickly to replace Mauresmo by reuniting with her predecessor, Ivan Lendl, under whom he won his two grand slam titles and Olympic gold.
The presence in his box of the stony-faced Czech-American has fostered hopes that Murray can stop the rot in slams against world number one Novak Djokovic after final defeats in Australia and Paris.
Lendl joined up with Murray's team again for the Aegon Championships at Queen's Club, where he won a record fifth title, and then oversaw a practice week, which went so well the world number two took the day off on Friday.
Murray said: "I don't feel any added pressure working with him again. I think it gives actually a bit of extra confidence, because I know last time we worked together, it was very successful.
"This last week's been very good. I've enjoyed having him back as part of the team. Hopefully I can have a good run here.
"Genuinely it was easy (slotting Lendl back into the team). He's obviously very clear in what he thinks and where my game needs to go if I want to keep improving and winning the major events again.
"Because I trust and believe in his opinion, it also helps when you get back on the court together. When we've chatted, it's all gone very well.
"I believe my practice this week has been good. My team's been happy with everything. If it wasn't going well, I probably wouldn't have had a day off today. I'm trying to refresh, recover a little bit, get ready for a big push the next couple of weeks."
It will be not just a busy couple of weeks but a hectic summer for Murray, who confirmed he is planning to play in both Britain's Davis Cup quarter-final immediately after Wimbledon in Serbia and the Rio Olympics.
Murray had sounded a note of caution about his gold medal defence when he said he would seek medical advice about the Zika virus.
He has now been reassured, with the 29-year-old saying: " I spoke to my doctor a bit and some of the guys on my team spoke to the doctor of British tennis, who has been working there for 35, 40 years.
"He seems to think that it's pretty safe and that we should be okay. I think probably when I'm done here, I'll have another chat with him, make sure. But my plan is still to play."
The Olympic tournament will be played on hard courts but Serbia have chosen clay for the Davis Cup, which appeared to make it less likely that either Murray or Djokovic would take part.
Djokovic has yet to commit either way but Murray said: " My plan's to play, providing I'm fit and feel good. Right now my body's good. Obviously I've played a lot of tennis. Hopefully I have a deep run here. That's the plan. Then I'll see obviously at the end of the event."
First up for Murray will be a new experience at Wimbledon - facing a British player.
The Scot had not played a countryman in singles for almost 10 years until he took on both Aljaz Bedene and Kyle Edmund at Queen's and now 22-year-old wild card Liam Broady stands in his way.
Murray said: " I know Liam fairly well. We practised a bit earlier this year. He's a good guy. Works hard. I would imagine we'd probably play on one of the big courts, so a big experience for him, as well.
"I'm looking forward to it b ut it will be a bit strange. It's never happened before for me."
